AB5 Operation 

13

 

3.2.1 Velocity 

Mode 

Operation 

In this operation mode, the motor is driven continuously by applying the analog 
command voltage (± 10 V) using a relevant interface device (joystick or motion 
controller). This is the driver default. 

3.2.2 Step 

Mode 

Operation 

In this operation mode, the driver output to the motor is turned on and off for fixed 
time intervals defined in the hardware as follows: 

ON phase - 1/16 second 
OFF phase - 0.5 second 

The amplitude of the output corresponds to the analog command input value and 
thus determines the speed of the motor. 

3.2.2.1 Enabling the Step Mode 

Short pin 16 to ground to enable Step mode operation. 

3.2.3 Brake 

On 

Mode 

 

This option is used when the inherent break force of the motor is needed.  The 
driver is disabled and the motor is turned off. (NOTE: although the driver is disabled, 
there is no reseting, as is the case when disabling is carried by the Emergency Stop 
or by the Enable_in inputs) 

3.2.3.1 Enabling the Break_on 

Short pin 17 to ground to enable the break. Disconnect it from ground to get the 
Break_Off.
