Drive Commissioning: Maximum Speed
References
Parameter Description
Max forward speed
Maximum forward reference to the speed regulator. This
maximum is enforced immediately prior to the speed
regulator and after all other speed offsets have been
summed into the reference path.
Max reverse speed Maximum reverse reference to the speed regulator. This
minimum is enforced immediately prior to the speed
regulator and after all other speed offsets have been
summed into the reference path.
Drive Commissioning: Jog Speed Setpoints
Enter the Jog speed setpoints:
When the drive is being jogged in remote mode, Remote jog speed supplants the
running reference during the time that the jog is commanded.
When the drive is being jogged in local mode, Local jog speed supplants the running
reference during the time that the jog button is held.
Drive Commissioning: Reference Ramp Bypass
The speed reference ramp function, which limits the rate of change of the speed
reference, may be disabled.
Select Yes to bypass the speed reference ramp. Select No to enable the ramp.

Drive Commissioning: Reference Ramp Mode
Two ramp modes are available for the speed reference ramp function, which differ in
the way the ramp rates are implemented:
• Indep accel/decel: Speed independent ramp rate mode.
• Prog accel/decel: Programmed ramp rate mode.
When the speed independent ramp rate mode is active, one acceleration rate and one
deceleration rate are implemented for all speeds. The rate of change of the speed
reference is limited to the acceleration rate when the magnitude of the speed
reference is increasing. The rate of change of the speed reference is limited to the
deceleration rate when the magnitude of the speed reference is decreasing.
