Issue Number: 3
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 0.048 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.
Entering 1253 or 1254 in Pr mm.000 will only load defaults if the setting
of Pr 00.048 has been changed.
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.
5.8 Restoring parameter defaults
Restoring parameter defaults by this method saves the default values in
the drives memory. User security status (00.049) and User security code
(00.034) are not affected by this procedure.
Procedure
1. Ensure the drive is not enabled, i.e. terminals 11 and 13 are open or
Pr 06.015 is Off (0)
2. Select 'Reset 50 Hz Defs' or 'Reset 60 Hz Defs' in Pr mm.000.
(alternatively, enter 1233 (50 Hz settings) or 1244 (60 Hz settings) in
Pr mm.000).
3. 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
5.9 Parameter access level and security
The parameter access level determines whether the user has access to
Menu 0 only or to all the advanced menus (Menus 1 to 41) in addition to
Menu 0.
The User Security determines whether the access to the user is read
only or read write.
Both the User Security and Parameter Access Level can operate
independently of each other as shown in Table 5-8.
Table 5-8 Parameter access level and security
The default settings of the drive are Parameter Access Level Menu 0
and user Security Open i.e. read / write access to Menu 0 with the
advanced menus not visible.
