TORQUE CONVERTER / INVERTER.
use for control starting load when this function is used the start torque converter compensation is set by command mechanical friction load , for the elevator.the setting of torque converter start torque rising time is in unit of Mr s(note )filter delay is disabled when the setting is between 0~4 ms
when this function is used the start torque converter compensation is set by command mechanical friction load , for the elevator , it will be set by the caring ability , friction load ,to be set as friction value in c 4- 03 , c 4- 04 . elevator onyx the electric side is set as caring ability for the elevator with balance weight please don,t use this function since the regeneration load will create shock.
only for the electric side,s compensation forward/ reverse can be both set (the regenerating side cannot be set ). when for/rev is switching the start torque compensation is disabled after speed research . start torque compensation is disabled when the second motor is used . in the occasion where start creates shock please increase the start torque converter compensation time constant (c 4 – 0 5) . if used the start current barking constant (b 2-03)
and the multi function Contactor input command the value is set to be 60,please pre-build magnetic field for the motor , the magnetic field can be build earlier when using start dc current barking constant (b 2-0 3).
TORQUE CONVERTER COMPENSATION GAIN IS SET IN UNIT OF MULTIPLE DO NOT ADJUST THE SETTING OF THIS CONSTANT FOR OPEN LOOP VECTOR CONTROL .
THIS CONSTANT CAN BE CHANGED DURING OPERATION BUT NORMALLY NO ADJUSTMENT ARE REQUIRED . WHEN THE CABLE IS LONG INCREASE THE SET VALUE . WHEN THE MOTOR CAPACITY IS SMALLER THAN THE INVERTER CAPACITY (MAX APPLICABLE MOTOR CAPACITY ) INCREASE THE SET VALUES . WHEN THE MOTOR IS OSCILLATING DECREASE THE SET VALUES. ADJUST THE OUTPUT CURRENT AT LOW SPREED TO BE LOWER THAN THE INVERTERS RATED OUTPUT CURRENT RANGE.
TORQUE CONVERTER COMPENSATION TIME CONSTANT./INVERTER
THE TORQUE CONVERTER COMPENSATION,S PRIMARY TIME DELAY IN UNITS OF MS ./INVERTER
THE TORQUE CONVERTER COMPENSATION TIME CONSTANT DOSE NOT NORMALLY NEED TO BE ADJUSTED BUT MAKE ADJUSTMENTS IN THE FOLLOWING CASES . IF THE MOTOR GENERATES IF THE MOTOR GENERATES EXCESSIVE OSCILLATION RAISE THE SETTING . IF MOTOR RESPONSIVENESS IS LOW LOWER THE SETTING.
