Description:
Gains of the current regulator, which must be set so as to optimize the dynamic response of the current loop.
In a general way, we can say the Proportional gain (P0167) stabilizes sudden current changes, whereas the
Integral gain (P0168/P0171) corrects the error between the torque reference and the effective current.
The use of each of the integral gains will be done automatically by the CTW900, according the output current
level:
■
for an intermittent armature current (motor with no load), the control will use the gain P0168;
■
for a continuous armature current (motor with load), the control will use the gain P0171;
In order to set these gains properly, follow the procedures described in sections 6.4.2.
P0172 – Variation Rate of the Torque Reference (Ia*)
Adjustable Range:
0 to 999 ms
Factory Setting:
20 ms
Properties:
Groups of

Description:
It defines the time for the torque reference (Ia* signal) to vary from zero to the maximum value, determined by
P0169/P0170 = 125 %.
