Figure 27 - Drive enable input circuit
In normal use, the drive enable input controls the enabled status of the drive. However, when the
MicroFlex e100 is connected to Mint WorkBench, additional methods are available for controlling
the drive enable status. In all cases, the drive enable input must be active and there must be no
errors present before the MicroFlex e100 can be enabled. It is recommended that an emergency
stop switch or emergency stop control system is incorporated in the drive enable circuit.
H
The 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 MicroFlex e100.
DRIVEENABLE(0)=0 will disable the
MicroFlex e100.
H
The Tools, Reset Controller menu item will clear errors and enable the MicroFlex e100.
Alternatively, the Mint command RESET(0) can be used in the command window to perform
the same action.
The state of the drive enable input is displayed in the Mint WorkBench Spy window.

Print DRIVEENABLESWITCH in the command window. See the Mint help file for details.
