The drive is developed for controlled ON-OFF driving and direction change of a DC-brushed motors
The drive has advanced current limit features
It limits the motor current in start-up and jam situations and that way protects the motor and mechanics from over torque
The drive also has an error output to indicate error / over current situations.,The acceleration ramp time for start-up is adjustable to suit different applications
In other word the motor voltage is slowly raised to give a smooth start-up
When the control is set to off, the motor is dynamically braked utilising short-circuit braking
The reverse and forward commands can be set for positive or negative control
The free-wheel command sets motor to run free
Free-wheel overrides both the forward and backward commands.,The current protection is double acting
First there is a continuous and adjustable current limit which decreases the motor voltage if the current exceeds the adjusted value
Second there is settable trip feature that cuts the motor voltage if the current limit value is exceeded (after trip delay 2ms)
After trip the motor starts only to the opposite direction
Additionally the driver doubles the adjusted current value for 0.3 seconds in start-up to ensure sufficient power to overcome the start-up friction
Fast change of direction Soft start-up, acceleration ramp Settable current limit Trip or continuous current limit Dynamic braking
