Only when the motor is cold!
A) Ensure that the controller is inhibited

Terminal X3/28 = LOW
B) Set C0148 = 1 Press v in addition
C) Enable the controller.

• Terminal X3/28 = HIGH
• The identification starts:
– The segment
c is off
– The motor consumes current and makes a
“high-pitched” tone.
– The motor does not rotate!
D) If the segment c becomes active after approx. 30 s, inhibit the
controller once again

• Terminal X3/28 = LOW
• Identification is completed.
• Calculated and stored:
– V/f rated fre quency (C0015)
– Slip compensation (C0021)
– Motor stator inductance (C0092)
• Measured and stored:
– Motor stator resistance (C0084) = Total
resistance of motor cable and motor
16. If necessary, adjust more parameters Activate e. g. JOG frequencies
(JOG) (C0037, C0038, C0039 or
motor parameter monitoring
(C0119)
After parameter setting:
17. Setpoint selection E.g. via potentiometer at
terminals7,8,9
18. Enable the controller.

In general, the vector control is ready for operation after the motor parameters
have been identified. Vectorcontrol must only be optimised forthe following drive
performance: 32
Drive performance Remedy
Rough motor run and motor current (C0054) > 60 %
rated motor current in idle running (stationary operation)
1. Reduction of motor inductance (C0092) by 10 %
2. Check of motor current under C0054
3. If the motor current (C0054) > 50 % of the rated
motor current:
– C0092 must be reduced until the mot or current
amounts to 50 % of the rated motor current
– Reduce C0092 by max. 20 %!
– Note: If you reduce C0092 the t o rque will decrease!
Torque too low for frequencies f < 5 Hz (starting torque) Increase of motor resistance (C0084) or increase of
motor inductance (C0092)
Poor constant speed at high loads (setpoint and motor
speed are not proportional).
Increase o f slip compensa t i on (C0021)
Overcompensation results in drive instability!
Error messages OC1, OC3, OC4 or OC5 during
acceleration times (C0012) < 1 s (drive controller is no
longer able to follow the dynamic processes)
Change readjustment time of the I
max
controller (C0078):
• Reduction o f C0078 = I
max
controller becomes quicker
(more dynamic)
• Increase of C0078 = I
max
controller becomes slower
