4.2.3 Motor control commissioning steps
The main commissioning steps are mentioned below in their ideal order. Correct assignment of the
inverter/motor and the mains voltage selection are assumed. Detailed information, especially for
optimisation of the current, speed and position control of asynchronous motors is described in the
guide "Control optimisation" (AG 0100). Detailed commissioning and optimisation information for
PMSM in CFC closed-loop mode can be found in the "Drive optimisation" guide (AG 0101). Please
contact our Technical Support.
1. Carry out the inverter and motor connection as usual (note ∆ / Y!). Connect the encoder, if present
2. Connect the mains supply.
3. Carry out the factory setting (P523)
4. Select the basic motor from the motor list (P200) (ASM types are at the beginning of the list, PMSM
types are at the end, designated by their type (e.g. …80T…))
5. Check the motor data (P201 … P209) and compare with the name plate / motor data sheet
6. Measure the stator resistance (P220) P208, P241[-01] are measured, P241[-02] is calculated.
(Note: If an SPMSM is used, P241[-02] must be overwritten with the value from P241[-01])
7. Encoders: Check the settings (P301, P735)
8. With PMSM only:
a. EMF voltage (P240) motor name plate / motor data sheet
b. Determine / set reluctance angle (P243) (not required with NORD motors)
c. Peak current (P244) motor data sheet
d. For PMSM in VFC mode only:
Determine (P245), (P247)
e. Determine (P246)
9. Select the operating mode (P300)
10. Determine / adjust the current control (P312 … P316)
11. Determine / adjust the speed control P310, P311)
12. With PMSM only:
a. Select the control method (P330)
b. Make the settings for the starting behaviour (P331 … P333)
c. Make the settings for the 0 pulse of the encoder P334 … P335)
d. Activation of slip error monitoring (P327 ≠ 0)
Further information for commissioning NORD IE5 motors with NORD frequency inverters can be
found in catalogue M5000 “Synchronous motors with IE5+ energy efficiency”.
