The drive enable input must be active and there must be no errors present before the
MotiFlex
e
100 can be enabled. Additional methods are required to enable the MotiFlex
e
100,
depending on the currently selected control reference source. The control reference source can
be selected on Mint WorkBench’s Motion toolbar. See also section 6.4.4.8.
H
If the control reference source is set to ‘Direct’, the Mint WorkBench drive enable button
on the motion toolbar toggles the enable/disable status. Alternatively, the Mint command
DRIVEENABLE(0)=1 can be used in the command window to enable the MotiFlex
e
100;
DRIVEENABLE(0)=0
will disable the MotiFlex
e
100.
The Tools, Reset Controller menu item will also clear errors and enable the MotiFlex
e
100.
Alternatively, the Mint command
RESET(0)
can be used in the command window to perform
the same action.
H
If the control reference source is set to ‘EPL’ or ‘CAN’, the respective fieldbus master
controls the drive enable status. Mint WorkBench cannot be used to control the drive enable
status until the control mode has been changed back to ‘Direct’.
The state of the drive enable input is displayed in the Mint WorkBench Spy window. Alternatively,
the state of the drive enable input can be read (but not set) using the Mint command
Print
DRIVEENABLESWITCH(0)
in the command window. See the Mint help file for details.
