Control mode change for a compound control mode
For a compound control mode, you can change between two basic control modes by setting
the parameter p29003 and configuring the level sensitive signal C-MODE on DI10.
0 (the first control mode)
1 (the second control mode)
6 PTI T
Refer to Section "DIs (Page 123)" for detailed information about DIs.
Note
Note that if p29003 = 5 and the motor has been working in speed control mode for a certain
period of time; or p29003 = 7 and the motor has been workin
g in torque control mode for a
certain period of time, the fault code F7493 might appear on the drive BOP. This, however,
will not cause the motor to stop. The motor remains operative under this circumstance and
you can clear the fault code manually.
Note
Fault F52904 occurs when the control mode is changed via p29003. You must save the
parameter and then re
-power on the servo drive to apply relevant configurations. For more
information about the remedy and acknowledgement of this fault, refer to Secti
on "List of
(Page 387)".
Note
Switching conditions
For the switching from PTI or IPos to S or T, you are recommended to perfo
rm control mode
switching after the INP (in position) signal is at high level.
For the switching from S or T to PTI or IPos, you can perform control mode switching only
after the motor speed is lower than 30 rpm.
