(e.g. H3-15=1) OYMC L7Z training

  25. >> FIRMWARE FUNCTIONS (FW 1030) • THE CORE : THE LIFT SEQUENCE (VII) • Sequence parameters are in the new S1 menu. OYMC L7Z training

  26. >> FIRMWARE FUNCTIONS (FW 1030) • SOME SEQUENCE EXAMPLES (I) • Output current and brake output signal. We can identify the DC Injection perfectly.. OYMC L7Z training

  27. >> FIRMWARE FUNCTIONS (FW 1030) • SOME SEQUENCE EXAMPLES (II) • Here we can see Contactor Output (blue), brake output (brown) and Output current (green). OYMC L7Z training

  28. >> FIRMWARE FUNCTIONS (FW 1030) • SOME SEQUENCE EXAMPLES (III) • Here we can see a sequence example taken with SDC V2.1 … From top : • Run signal (Up) • Brake • Contactor • Frequency Output OYMC L7Z training

  29. >> FIRMWARE FUNCTIONS (FW 1030) • SPEED SELECTION (I) • THE SPEED PRIORITIES AND FV COMPATIBILITY MODE • The L7Z provides several sequence behaviour selection to allow FV update, old 2 speed systems update, new multispeed systems, etc… with minimum wiring. • Unfortunately, in FV compatibility mode some special functions related with the levelling speed selection are not possible in firmware 1030 (as the inverter is not aware of which is the levelling speed) : Short floor, feedforward slip, feedforward DC injection, etc. • TO GET MAXIMUM BENEFIT FROM Firmware 1030 use D1-18=1 or 2 !! • Also they provide increased sequence safety OYMC L7Z training

  30. DC DC Injection/ Injection/ zero servo zero servo speed Hardware BB Up/Down leveling no effect selected speed input is set DC DC Injection/ Injection/ zero servo zero servo speed Hardware BB Up/Down leveling speed leveling speed has priority selected speed >> FIRMWARE FUNCTIONS (FW 1030) • SPEED SELECTION (II) • PRIORITIES DEFINED AS FOLLOWS D1-18=1 is preferred type for safety : • D1-18 = 1 (high speed has priority) levelling STOPS. If levelling command is not configured, Up/Down STOPS. wires break = levelling • D1-18 = 2 (levelling has priority) levelling STOPS. If nominal command is not configured, Up/Down STOPS. wires break = nominal !!!!! OYMC L7Z training

  31. >> FIRMWARE FUNCTIONS (FW 1030) • SPEED SELECTION (III) • With D1-18=0, standard FV multifunction input values are available • With D1-18=1, New specific speed reference parameters with specific names are available. New multifunction values are available. OYMC L7Z training

  32. Inspection RUN DC DC (NO) Injection/ Injection/ zero servo zero servo speed speed Hardware BB Up/Down (D/I) Up/Down (D/I) Inspection RUN Inspection RUN base block base block MC closed (D/O) MC closed (D/O) Brake opened (D/O) Brake opened (D/O) >> FIRMWARE FUNCTIONS (FW 1030) • SPEED SELECTION. Inspection speed (IV) • The inspection speed has associated a specific typical inspection sequence Inspection RUN (NO) Hardware BB • RUN + Inspection speed terminal = start sequence. • The inverter coasts to stop during the inspection mode,. • The falling edge of the inspection RUN command or UP/DOWN commands triggers the contactor open command , the motor brake close command and the Baseblock. OYMC L7Z training

  33. >> FIRMWARE FUNCTIONS (FW 1030) • DECELERATION AND S-CURVE SETTINGS • C1-11 changes decel time from C1-02 to C1-08 only in decel section. C1-02 C1-01 C1-11 C1-08 • Additional S-Curve setting C2-05 for STOP. Very useful to modify stopping point without affecting deceleration ride quality. C2-03 C2-02 C2-04 C2-05 C2-01 OYMC L7Z training

  34. >> FIRMWARE FUNCTIONS (FW 1030) • NEW LIFT SEQUENCE FAULT MESSAGES • SE1 : Contactor feedback fault. If multifunction is set to 86 (Output Contactor feedback), then SE1 might appear : • CASE 1: Output contactor of output inverter kept closing before contactor closed command set. • CASE 2: Output contactor cannot be closed within the contactor close delay time. • CASE 3 :Output contactor is opened during inverter running. • SE2 : On brake release, the inverter checks if the motor current is higher than 25% of No-Load current. If not SE2 error is generated • SE3 : During RUN, the inverter checks if motor current is higher than 25% of No-Load current. If not, SE3 error is generated. OYMC L7Z training

  35. measure apply >> FIRMWARE FUNCTIONS (FW 1030) • FEEDFORWARD SLIP COMPENSATION (OLV / VF) (I) • After 1s at speed agree (nominal), the inverter makes an average of motor current (VF) or torque reference (OLV). This will be applied during levelling. • Only works with D1-18<>0 with firmware 1030 • The compesation differentiates regen and motoring. • Very, very useful in open loop for levelling accuracy. • New monitor U1-50 (slip comp. monitor) helps greatly to check how it works OYMC L7Z training

  36. >> FIRMWARE FUNCTIONS (FW 1030) • DC INJECTION (OLV / VF) (I) • DC Injection level (OLV and VF) and time (all methods) at Start and Stop can be set independently. • DC Injection times in FVC are zero speed hold times OYMC L7Z training

  37. ASR P,I ASR P,I C5-09 ASR Gain 3 C5-01 ASR Gain 1 C5-10 ASR I Time 3 C5-02 ASR I Time 1 C5-03 ASR Gain2 C5-03 ASR Gain2 C5-04 ASR I time 2 C5-04 ASR I time 2 0Hz 0Hz Speed(Hz) Speed(Hz) During Acceleration During Deceleration >> FIRMWARE FUNCTIONS (FW 1030) • 3 ASR (Automatic Speed Regulator) SETS (FVC) • L7Z allows selection of different ASR settings when starting, during top speed (E1-04 max freq. is the reference) and when stopping. This allows the most accurate settings. 50 ASR gain brake ASR gain levelling, opening zero speed 20 ASR gain top speed 0 OYMC L7Z training

  38. Internal RUN 300% torque Latch Torque comp.at start level >> FIRMWARE FUNCTIONS (FW 1030) • DWELL AT START FUNCTION • When S1-26 ( dwell speed reference ) is set , the Dwell at start function is activated. When the inverter starts, the inverter accelerates to S1-26 speed with C1-07 acceleration time. Once the motor speed exceeds the C1-11 frequency, the inverter will use the original acceleration. Dwell at start function C1-07 S1-26 • Original Dwell function (b6) is still available. Soft Starter Motor speed C1-11 Brake release OYMC L7Z training

  39. >> FIRMWARE FUNCTIONS (FW 1030) • INERTIA COMPENSATION (Speed feedforward) (FVC) • L7Z ads a feedforward term to the ASR control. When correctly tuned, overshoots due to inertia component of the machine are eliminated. • This becomes specially important as the gear ratio is reduced. • The tuning procedure is : • With balanced car, accelerate from zero to nominal speed with acceleration settings such that torque demand is continuous rated torque during acceleration. Measure the time and place in N5-02 OYMC L7Z training

  40. Speed Vs Vn Vn*0.4 Vl S2 Vj t 0 T1 T2 T1 T2 >> FIRMWARE FUNCTIONS (FW 1030) • SHORTFLOOR OPERATION • L7Z calculates estimated area (distance) from Vn to Vl with current parameters. • When levelling command is received, if actual speed is below 40% of Vn then the inverter keeps 40% reference for a calculated time to achieve the estimated area and reduce levelling time. The inverter keeps running at 40% of Vn reference until The S2 remaining area becomes Like S’ area. Speed Vn: nominal speed Vl: levelling speed T1:S-curve time at top T2:S-curve time at stop S = area Vstd VnX0.4 S s' s' t 0 T1 T2 OYMC L7Z training

  41. >> FIRMWARE FUNCTIONS (FW 1030) • NEW MONITORING FUNCTIONS • L7Z adds some other useful monitors. A group to check current behaviour during the car travel and a number of travels counter. In 1030 D1-18<>0. • LIMIT SWITCH INPUTS OYMC L7Z training

  42. >> FIRMWARE FUNCTIONS (FW 1030) • MULTIFUNCTION OUTPUTS • Door Open is already registered by other company, so we have to give a different name. OYMC L7Z training
