Function Code Parameter Name Setting Range Default Unit Property
F3-18 Zero-speed control time at startup 0.000–1.000 0.200 s
★
F3-19 Brake release delay 0.000–1.000 0.600 s
★
F3-20 Zero-speed control time at end 0.200–1.500 0.200 s
★
These parameters are used to set the time related to the zero-speed holding current output
and braking action delay.
• F3-18 (Zero-speed control time at startup) specifies the time from output of the RUN
contactor to output of the brake contactor, during which the controller performs excitation
on the motor and outputs zero-speed current with large startup torque.
• F3-19 (Brake release delay) specifies the time from the moment when the system sends
the brake release command to the moment when the brake is completely released,
during which the system retains the zero-speed torque current output.
• F3-20 (Zero-speed control time at end) specifies the zero-speed output time when the
running curve ends.
• F8-11 (Brake apply delay) specifies the time from the moment when the system sends
the brake apply command to the moment when the brake is completely applied, during
which the system retains the zero-speed torque current output.

It is used to set the elevator speed of returning to the leveling position at normal non-leveling
stop.
