44 Unidrive M702 Getting Started Guide
Issue Number: 4
5.6 Changing the operating mode
Changing the operating mode returns all parameters to their default value, including the motor
parameters. User security status (00.049) and User security code (00.034) are not affected by this
procedure).
Procedure
Use the following procedure only if a different operating mode is required:
1. Ensure the drive is not enabled, i.e. terminals 11 and 13 are open or Pr 06.015 is Off (0)
2. Enter either of the following values in Pr mm.000, as appropriate:
1253 (50 Hz AC supply frequency)
1254 (60 Hz AC supply frequency)
3. Change the setting of Pr 00.048 as follows:
The figures in the second column apply when serial communications are used.
4. Either:
• Press the red reset button
• Toggle the reset digital input
• Carry out a drive reset through serial communications by setting Pr 10.038 to 100.
5.7 Saving parameters
When changing a parameter in Menu 0, the new value is saved when pressing the Enter
button to return to parameter view mode from parameter edit mode.
If parameters have been changed in the advanced menus, then the change will not be saved
automatically. A save function must be carried out.
Procedure
1. Select ‘Save Parameters'* in Pr mm.000 (alternatively enter a value of 1000* in Pr mm.000)
2. Either:
• Press the red reset button
• Toggle the reset digital input, or
• Carry out a drive reset through serial communications by setting Pr 10.038 to 100
* If the drive is in the under voltage state (i.e. when the control terminal 9 and 10 are being supplied
from a low voltage DC supply) a value of 1001 must be entered into Pr
mm.000 to perform a save
function.

Entering 1253 or 1254 in Pr mm.000 will only load defaults if the setting of Pr 00.048 has
been changed.
