Operation
3.1 Set
Offset
Procedure
Set Offset calibrates the “zero command” for each specific motor and system. Each
new motor should be calibrated using the Set-Offset procedure before being used.
This is necessary to prevent slide movement when the zero command is applied.
3.1.1 Setting
the
Offset
1. Toggle Enable off and then on again before starting the adjustment.
2. Apply the zero command and see if there is slide movement.
3. Adjust the command voltage level until the slide movement stops.
4. While still applying the above command level, momentarily short pin 19 to
ground. The driver “remembers” this level of command as its zero. (Max 2.5V )
5. Apply now zero command level and verify that the slide is in standstill.
3.2 Operation
Modes
Both Enable_In and Motor_Connected inputs must be active for operation,
regardless of the operation mode.
The AB5 can be operated in one of the three operation modes listed below.
Velocity (AC) Mode
, in which the motor is driven continuously.
Step Mode
, in which the driver output is turned OFF and ON at hardware,
predefined intervals, thus driving the motor in discrete steps.
Brake On Mode
, while in Velocity Mode,enables holding force to be turned ON or
OFF, as desired by the user.
