Torque (Current) Limiting Adjustment
The TORQ trim potentiometer (Figure 1) has been calibrated so that the motor
will never see more than 200% to 250% of its rated current input. The motor’s
torque output can be reduced to zero or stall torque. Set the torque based
on the system load requirements. Torque may be reduced on lightly loaded
systems to protect drive mechanisms, such as gearing, from damage due to
overloads. Turn the TORQ trim potentiometer counterclockwise to decrease
the torque and clockwise to increase the torque.
Acceleration Adjustment
Adjusting the ACCEL trim potentiometer (See Figure 1) counterclockwise
decreases the motor’s acceleration time down to a minimum of approximately
0.2 seconds (ABL-3912E) or 0.5 seconds (ABL-3913E). A clockwise adjustment
increases the rate up to a maximum of approximately 10 seconds (ABL-3912E)
or 30 seconds (ABL-3913E).
Deceleration Adjustment
Adjusting the DECEL trim potentiometer (See Figure 1) counterclockwise
decreases the motor’s deceleration time down to a minimum of approximately
0.2 seconds (ABL-3912E) or 0.5 seconds (3913E). A clockwise adjustment
increases the rate up to a maximum of approximately 10 seconds (3912E) or
30 seconds (3913E).
