Setting 7: Preset 7 - YASKAWA CIMR-VU BA0001 Technical Manual

4.6 Application Selection
<1> This is the setting recommended when using Open Loop Vector Control. In V/f Control, set the level as the motor rated slip frequency plus 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 is greater than the minimum
output frequency and greater than the value of L4-02 as shown in the diagram below. If set too high, however, there may be a jolt at start.
<2> Hysteresis for Frequency Detection 2 can be adjusted by changing the Frequency Detection Width (L4-02) between 0.0 and 0.5 Hz. If the load slips
during stop, make changes in steps of 0.1 Hz until the load no longer slips.
The braking sequence should be designed as follows:
• A normally open signal (N.O.) should be used to control the brake so that it is released when terminal P2-PC closes.
• When an Up or Down command is entered, the brake should release.
• When a fault signal is output, the brake should close.
• When changing the speed using an analog signal, make sure that the source of the frequency reference is assigned to the
control circuit terminals (b1-01 = 1).
• A sequence to open and close the holding brake appears in the diagram below.
