Simulator

The Simulator function allows the user to simulate the operation of the drive and

motor without applying power to th e motor, power bridge, and other equipment.

Function inputs

The following table specifies the input parameters of the Simulator function.

Parameter Description
Ext sim spd enb sel Select s the signal tha t disables the cal culated model
speed and allows the speed to be specified by another
source.
Ext sim spd sel S elects the vari able motor speed t hat overrides t he speed
calculati on. RPM
Ext sim trq sel Selects the variable torque produced by an external load.
Newton-meters
Function outputs

The following table specifies the output variables of the Simulator function.

Variable Description
Simulated s peed Mot or speed. Radia ns/second
Function configuration

The following table specifies the configuration parameters of the Simulator function.

Parameter Description
