[Multi-Step Frequency Operation]
☞
Note: The frequency for ‘Speed 0’ is determined by DRV-04.
[XCEL-L, XCEL-M, XCEL-H]
By setting P1, P2 and P3 terminals to ‘XCEL-L’,
‘XCEL-M’ and ‘XCEL-H’ respectively, up to 8
different Accel and Decel times can be used. The
Accel/Decel time is set in DRV-01 ~ DRV-02 and
I/O-25 ~ I/O-38.
The Accel/Decel time is determined by the
combination of P1, P2 and P3 terminals as shown
in the following table.

[Multi-Accel/Decel Time Operation]
[DC-Brake]
DC Injection Braking can be activated during
inverter stopped by configuring one of the multi-
function input terminals (P1, P2, P3) to ‘DC-Bake’.
To activate the DC Injection Braking, close the
contact on the assigned terminal while the inverter
is stopped.

nd
Function]
Inverter uses parameters set in FU2-81 ~ 89
when this terminal is ON. This function must be
used when motor is stopped to avoid over current
