For the parameterization of P-0-0510, Rotor inertia use the values from
the completed form "Output data for Asynchronous or Synchronous
Motors".
The controller can directly evaluate frequently used temperature sensors
because the resistance characteristics of the sensors are stored in the
firmware. For P-0-0512, Temperature sensor the value for the
temperature sensor installed in the third-party motor has to be entered. If
the resistance characteristic has not been stored, it can be stored in
parameter P-0-0513, Temperature sensor characteristic.
The motor shutdown temperature depends on the insulation class of the
motor. The motor warning temperature should be at least 10 K below the
motor shutdown temperature. These threshold values have to be set
according to the insulation class of the third-party motor in the parameters
S-0-0204, Motor shutdown temperature or S-0-0201, Motor warning
temperature.
The voltage loop is used to control the motor voltage in the field-
weakening range. For synchronous motors the value for P-0-0533,
Voltage loop proportional gain is determined by:
−
P
P-0-0533: voltage loop proportional gain (in V/A)
S-0-0106: current loop proportional gain 1 (in V/A)
