Chapter 7 Parameter Table of Integrated Drive Controller
F230—— compensation torque gain. The frequency convertor calculate the actual torque
compensation value on the basis of the compensation value given by the control
system and also increased/decreased by the F230 parameter gain, when there is
startup pre-load compensation function.( when F230 bigger than 100 is referred to as
increase. When F230 smaller than 100 is referred to as decrease. ) . Set the parameter
in accordance with the following principle. If the compensation is not enough, the
value increase is required. When the compensation is too much, the value decrease is
required. The insufficient compensation refer to the phenomenon of full-load
downward impact(slippage when upward, acceleration when downward ) and the
light-load upward impact (slippage when downward, acceleration when upward). The
overcompensation refer to the phenomenon of full-load upward impact (slippage
when downward, acceleration when upward) and light-load downward impact
(slippage when upward, acceleration when downward)
F231—— compensation torque offset. The parameter work when there is startup pre-load
compensation function. The parameter is set in the following way.
When car and counterweight reach complete balance, the inspection speed is set as 0.
Meanwhile, the car should remain still while handling the elevator inspection
operation. If the car is active, the parameter should be set until the car reach complete
still while doing the inspection operation.
F232—— encoder feedback signal filtering time parameter. The default value is 0. Only when
on-site interference is very serious, properly expansion the filtering duration will
increase the anti-interference capacity of the system.
F233—— encoder feedback direction. 0: negative sequence. 1: positive sequence. The default
value is 1. Under the normal circumstance, there is no need to change the value. But if
the feedback direction is directly opposite to the actual direction due to the wrong
encoder wiring, set the parameter F233 to adjust it.
F234—— motor phase sequence, the default value is 1. but if it is found that the rotating
direction of motor is directly opposite to the required rotating direction, set the
parameter F234 from 1 to 0 to reverse the direction of motor.
F235—— motor none-load current parameter, set the proportion value of tractor non-load
current in term of rated current . The default value is 32%. Under the normal
circumstance, there is no need to change the value.
F236—— PWM carrier frequency. The higher the carrier frequency is, the smaller the noise of
the motor is, the more the lost will be. Under the normal circumstance, there is no
need to change the setting, just use the default value (6KHz). Since the increase in the
carrier frequency will aggravate the waste of frequency converter, so if there is on-site
need to reduce the motor noise by increasing the carrier frequency and the increased
carrier frequency exceed the default value, the frequency converter need to be derated
by 5% for every 1KHz increase.
F237—— PWM carrier frequency width. Under the normal circumstance, users only need to
operate with the default value. To change automatically the carrier frequency within
the width range so as to reduce the motor noise in some situation. For example, the
setting value of F236 is 6KHz, the setting value of F237 is 0.4KHz. the actual carrier
frequency of frequency converter change automatically within the scope of 5.8~
