Use forward-running timing sequence as example:
Start: When the VFD is in standby state, the brake
output signal is closed. After receiving the running
command, the VFD accelerates with the target
frequency P90.16. In addition, the VFD starts
torque verification, if the verification is OK
(condition: output current>= P90.12 (it is P90.13 in
reverse running) and output torque >= P90.14 (it is
P90.15 in reverse running), output frequency is at
least equal to P90.16 (it is P90.17 in reverse
running), the delay before forward brake release
starts, and the VFD outputs the brake release
signal when P90.20 (or P90.21 in reverse running)
is reached. Then the delay after forward brake
release starts. The VFD normally accelerates to
the set frequency within the time specified by
P90.22 (or P90.23 in reverse running).
Stop: To prevent hook slip, sufficient output torque
must be ensured before brake is closed. After
receiving the stop command, the VFD decelerates
