Utilising dual motor set-up

The Commander SE has the ability to control 2 different motors of different ratings, so long as they are both within the
specification of the drive. Only one motor can be controlled at any one time. The motor 2 parameters should be entered in
Menu 21.
A digital input should be programmed to 11.45 to select the second motor map. The second motor map will only be
implemented when the drive is in the inhibit, ready or tripped modes.
A parameter in Menu 21, 21.15, will change from a 0 to a 1 when the second motor map is implemented. This can be used to
change a changeover relay which intern will select the correct motor contactor.
See diagram on the next page.
Parameter set-up
8.39 = 1
8.26 = 11.45
8.21 = 21.15
Perform a Save routine: xx.00 = 1000 and press red Stop / Reset button on the drive
Enter motor 1 nameplate details into motor map parameters in level 1 or Menu 5 with motor 1 selected and perform an
autotune (0.38 = 1[non rotating] or 2 [rotating])
Enter motor 2 nameplate details into motor map 2 in Menu 21 and with motor 2 selected perform an autotune (0.38 = 1[non
rotating] or 2 [rotating])
Operation
When the switch on terminal 13 is open, the external relay will be de-energised and therefore the contactor to motor 1 will be
closed.
If the drive is running and the switch on terminal 13 is closed, the contactor to motor 1 will remain closed. If the drive is
stopped or disabled, the external relay will energise and open the contactor to motor 1 and close the contactor to motor 2.
This set-up ensures that the drive is disabled when the contactors are opened or closed.
