How To Change a Parameter Value
You can change the values of parameters stored in the
and
menus. Refer to Chapter

View the parameter to be edited and press
to display the parameter’s value.
Select the digit to be changed (pressing the
key moves the cursor from right to left).
Use the
keys to adjust the value. Hold the key momentarily to adjust the value
marginally, or hold the key to make rapid changes; the rate of change varies with the time
held.
Press
to return to the parameter display. The new value is stored.

Selecting Local or Remote Control
The drive can operate in one of two ways:
Remote Control:
Allowing access for application programming using digital and
analog inputs and outputs
Local Control:
Providing local control and monitoring of the drive using the
Keypad
Local control keys are inactive when Remote Control is selected.
In Remote Control, the drive uses a remote setpoint. In Local Control, it uses the Local Setpoint
parameter whose value is adjusted on the MMI.
Note:
You can only change between Local and Remote Control when the drive is “stopped”,
and either
or the Local Setpoint is displayed.
