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:

01060S/105330P −−=−−

P-0-0533: voltage loop proportional gain (in V/A)

S-0-0106: current loop proportional gain 1 (in V/A)
