Description
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
frequency is at least equal to
P90.17 in reverse running), the delay before
forward brake release starts, and the VFD
outputs the brake release signal when
(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
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 to P90.28
frequency within P90.29. When output
frequency <= P90.18
running), the delay before brake release starts.
When the delay reaches
reverse running), the VFD outputs brake closing
signal. The delay after brake release starts. The
VFD decelerates to zero and stops within the
