[TstGen Output]
Allows you to select a simulated parameter as the output for the test
generator. The test generator is used to manually tune the regulators. It
consists of a square wave generator whose frequency, offset and amplitude
can be manipulated.
• “NotConnected” - No internal parameters defined by the generator.
• “Reserved” - Not used.
• “Torq Cur Ref” - The output of the generator defines the reference value of
the torque current. 100% corresponds to “full load torque current” (FLT).
• “Field Ref” - The output of the generator defines the field reference value.
100% corresponds to the rated field current based on the motor
nameplate data parameters.
• “Ramp Ref” - The output of the generator defines the ramp reference
value. 100% corresponds to the value specified in Par 45 [Max Ref Speed].
This is the value immediately before the Ramp function.
• “Speed Ref” - The output of the generator defines the speed reference
value. This is the value immediately before the Speed Regulator function.

ATTENTION: Uncontrolled machine operation could result with a motor connected during these tests and may cause
personal injury and/or equipment damage. Verify that the drive is not connected to a motor armature circuit before
enabling these test modes.
