LinearAmpVoltageClamp Parameter
Default Value: 0
Minimum Value: 0
Maximum Value: 80
Units: volts
Type: float
HARDWARE: This parameter applies only to the iXL2e, XL2e, iXL5e, XL5e, iXR3 with an XSL3 amplifier, and XR3 with an XSL3 amplifier.
Use the LinearAmpVoltageClamp parameter to specify the maximum voltage command that the drive will output. The controller uses the value that you specify for this parameter to clamp the maximum positive and minimum negative voltage output on each motor phase.
To minimize the amount of heat that the internal linear amplifier creates, use the lowest possible bus voltage for your application and set the LinearAmpVoltageClamp parameter to the voltage value of your connected bus. For example, if you have a +/-24V bus voltage, specify 24V for the LinearAmpVoltageClamp parameter. The voltage output will be clamped between -24V and +24V on each phase. If you use sufficient bus voltage, the voltage clamp should not activate with typical operation.
If you set the LinearAmpVoltageClamp parameter to 0, or if you set it to a value greater than the maximum amplifier output for your drive, the controller does not clamp the output voltage. You do not need to set the LinearAmpVoltageClamp parameter to protect the amplifier, but this parameter lets the controller detect when the connected bus voltage is not sufficient. If the amplifier clamps the output voltage, the Voltage Clamped bit of the AmplifierStatus axis status item shows this condition.
