Figure 28 - Drive enable input circuit
In normal use, the drive enable input controls the enabled status of the drive. However, when
the MicroFlex 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 can be enabled.
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;
DRIVEENABLE.0=0
will disable the MicroFlex.
H
The Tools, Reset Controller menu item will clear errors and enable the MicroFlex.
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.
Alternatively, the state of the drive enable input can be read (but not set) using the Mint
command
Print DRIVEENABLESWITCH
