Frequency L4-07 = 0
Detection 2 H2-03 = 5
<1> This setting range is available when using OLV Control. In V/f Control, set the level as the motor rated slip
frequency pulse 0.5 Hz. Not enough motor torque will be created if this value is set too low, and the load may tend
to slip. Make sure this value greater than the minimum output frequency and greater than the value of L4-02 as
shown in the diagram below. If this value is set too high, there may be a jolt at start.
<2> Adjust Hysteresis for Frequency Detection 2 by changing the frequency detection width (L4-02) between 0.0 and
0.5 Hz. If the load slips during stop, make incremental changes of 0.1 Hz until the load no longer slips.

Sequence Circuit Design for Opening and Closing the Holding Brake

Design the braking sequence as follows:
The brake should release when terminal P2-PC closes in response to the run conditions on
the sequence side.
When a fault signal is output, the brake should close. When an up or down command is
entered, the brake should release.
