Stall Protection and Jam Detection
The SMC Dialog Plus controller provides both stall protection and
jam detection for enhanced motor and system protection.
Stall protection is user-adjustable from 0.0 to 10.0 seconds (in
addition to the ramp time programmed).
Jam detection allows the user to determine the jam level (up to
999% of the motor’s FLC rating) and the delay time (up to 10.0
seconds) for application flexibility.
