SPEED COMMAND
Discrete Speeds
267 [TB Manual Ref]
Reference value for the drive when the Terminal Block asserts Manual
reference control.
Notes: This parameter can be assigned to an analog input. See Reference
Control on page 307
for more information.

The value of [Max Ref Speed] cannot exceed 6000 rpm.
1409 [Jog Off Delay]
Specifies the amount of time that will elapse between removing the Jog
input and commanding the main contactor to open. The amount of time
specified in [Jog Off Delay] will not begin to elapse until the measured speed
feedback is less than or equal to the value of parameter 107 [Speed Zero
Level]. This delay reduces the wear on the contactor when repeatedly
opening and closing the Jog input over a short period of time. If a stop
command is asserted before the jog off delay time has completed, the drive
will stop and the delay timer is cancelled.
Note: This parameter was added for firmware version 2.001.
