Slip Frequency Compensation - Veichi Electric AC60 series Manual

1：module temperature correlation is valid
When inverter temperatures rise, frequency inverter automatically reduces
the carrier frequency; When inverter temperature reduces, carrier frequency
will rise. This function can help the frequency inverter to reduce the switch
loss of the power device to prevent frequent alarms for inverter overheat fault.
LED 100 digit：PWM mode selection
0：Fixed PWM mode Motor noise frequency is fixed.
1：Random PWM mode This mode enables the harmonic spectrum of inverter output
voltage evenly distributing in a wide frequency range to inhibit the electrical
noise and vibration effectively.
LED 1000 digit：Reserved
E-22 Slip frequency
compensation
This function enables that the output frequency of the frequency inverter
automatically adjust in the setting range according to the change of the load;
Dynamic compensate the slip frequency, thereby ,it enables the motor
maintaining a constant rotate speed to reduce the load change impact on the
motor speed effectively.
If cooperate with automatic torque upgrade functions, the low frequency
torque characteristic of inverter will be significantly improved. Slip
