• Set Pr.154 = "10 or 11" when the overvoltage protective function (E.OV) is activated during stall prevention operation in
an application with large load inertia. Note that turning OFF the start signal (STF/STR) or varying the frequency command
during stall prevention operation may delay the acceleration/deceleration start.
1 (initial value)
• Do not set the stall prevention operation current too low.
Doing so will reduce the generated torque.
• Be sure to perform the test operation.
Stall prevention operation during acceleration may extend the acceleration time.
Stall prevention operation during constant-speed operation may cause sudden speed changes.
Stall prevention operation during deceleration may extend the deceleration time.
