621 CL: Startup torque
(2.6.18.11)
Choose here the startup torque.
Torque Memory is used in crane applications. Startup Torque FWD/REV can be used in
other applications to help the speed controller. See chapter 9.1.
0 = Not Used
1 = TorqMemory
2 = Torque Ref
3 = Torq.Fwd/Rev
626 CL: Acceleration compensation
(2.6.18.5)
Sets the inertia compensation to improve speed response during acceleration and
deceleration. The time is defined as acceleration time to nominal speed with nominal
torque. This parameter is active also in advanced open loop mode.
627 CL: Magnetizing current at start
(2.6.18.7)
628 CL: Magnetizing time at start
(2.6.18.8)
Set here the rise time of magnetizing current.
631 Identification
(2.5.16)
Identification Run is a part of tuning the motor and the drive specific parameters. It is a
tool for commissioning and service of the drive with the aim to find as good parameter
values as possible for most drives. The automatic motor identification calculates or
measures the motor parameters that are needed for optimum motor and speed control.
0 = No action
No identification requested.
1 = Identification without motor run
The drive is run without speed to identify the motor parameters. The motor is supplied
with current and voltage but with zero frequency.
2 = Identification with motor run
The drive is run with speed to identify the motor parameters.
Note: It is recommended to do the this identification test with no load on the motor for
best results.
The basic motor name plate data has to be set correctly before performing the identifi-
cation run:
ID110 Nominal voltage of the motor (par. 2.1.6)
ID111 Nominal frequency of the motor (par. 2.1.7)
ID112 Nominal speed of the motor (par. 2.1.8)
ID113 Nominal current of the motor (par. 2.1.9)
ID120 Motor cos phi (par. 2.1.10)
When in closed loop and with an encoder installed, also the parameter for pulses /
revolutions (in Menu M7) has to be set.
