6 Installation Startup and Autotune Guides
36 MAGNETEK HPV1000 AC Elevator Drive Technical Manual
The drive will then automatically populate the following parameters in the A1 and A5 menus:
• Encoder Pulses(A1)
• Rated Mtr Power (A5)
• Rated Mtr Volts
• Rated Motor Freq (A5)
• Rated Motor Curr (A5)
• Number of Poles (A5)
• Motor Rated Slip (A5) - calculated from autotune
• No-Load Current (A5)
• Leak Inductance (A5) - calculated from autotune
• Term Resistance (A5) - calculated from autotune
Low-Speed Inspection Mode
Run the drive in low-speed inspection mode and:
• Start with default values for INERTIA (A1)
• Verify encoder polarity. The motor phasing should match the encoder phasing. If you experience ENCODER FAULT/
HIT TRQ LIM alarm the phasing may be incorrect. This can be reversed changing ENCODER CONNECT (C1)
between C.W (clockwise) and C.C.W (counterclockwise).
• Verify proper hoistway direction can be reversed with the MOTOR ROTATION and ENCODER CONNECT (C1)
parameters.
