Parameter Descriptions
● L PREF: 134.17 Default: 24.299 Range: 0.000 to 1000.000 mH
Set the motor’s inductance at maximum current. This parameter is used within the current loop and is related to the overall proportional gain.
PHASE
PREF: 134.18 Default: 0.00 Range: 0.00 to 90.000 degrees
Set the motor’s phase shift advance at permanent current. If this parameter is unknown, value must be set to 0.
The current setpoint I is separated into two current setpoints Iq and Id, obeying the following rule :
MAX PHASE PREF: 134.19 Default: 0.00 Range: 0.00 to 90.000 degrees
Set the motor’s phase shift advance at maximum current. If this parameter is unknown, value must be set to 0.
The current setpoint I is separated into two current setpoints Iq and Id, obeying the following rule - see
PHASE above.
MAX TORQUE PREF: 134.20 Default: 12.80 Range: 0.00 to 30000.00 Nm
Set the motor’s torque at maximum current.
● KT PREF: 134.21 Default: 1.376 Range: 0.0000 to
100.0000
Nm/A
Torque constant (Kt, Nm/A rms).
This parameter is used to compute the current demand given a torque demand :
Current demand = Torque demand / KT
In order to have correct feedbacks the following equation MUST be true:
PERM TORQUE = KT * PERM CURRENT
