Chapter 3 Paramters/Functions Innovation Series Medium Voltage GP Type - G Drives GEH-6385
Simulator
The Simulator function allows the user to simulate the operation of the drive and
motor without applying power to the 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
Selects the signal that disables the calculated model
speed and allows the speed to be specified by another
source.
Ext sim spd sel Selects the variable motor speed that overrides the speed
calculation. 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 speed Motor speed. Radians/second
Function configuration
The following table specifies the configuration parameters of the Simulator function.
Parameter Description
Simulate mode Enables drive and motor simulation.
