MOTOR CONTROL
P304 - Skip Frequency 2
Range: 0.0 to 400.0 Hz
Properties: V/f, VVW
Description:
These parameters represent the center of the frequency range avoided, according to Figure 8.11 on page 8-14.
P306 - Skip Band
Range: 0.0 to 25.0 Hz
Properties: V/f, VVW
Description:
The actuation of those parameters is done as presented in Figure 8.11 on page 8-14 below. The passage by the
skip frequency band (2 x P306) is done through acceleration/deceleration ramp. The function does not operate
correctly if two bands of ”Skip Frequency” overlap.

8.1.7 Fire Mode
The “Fire Mode” function is intended to make the frequency inverter continue to drive the motor even under adverse
conditions, inhibiting most faults generated by the frequency inverter. The “Fire Mode” is activated by driving a digital
input previously set to “Fire Mode” with logic level “0” at the input terminals. When the drive enters the“Fire Mode”,
the alarm “A211” will be generated on the HMI (keypad) and the status of the operation mode will be updated in
parameter P006.
