5) CON_35 (Torque Balance)
In the lift use, the load torque balance can be adjusted to obtain a good riding comfort at start-up using the load cell,
which is a sort of an weighing devices installed at the bottom of the lift. CON_35 is adjusted to show 50% after the car
weight becomes equal to the weight of counter-weight.
The value displayed when pressing [PROG] key on the keypad is the loadcell voltage input to the inverter. Therefore,
adjust the percent using [
▲(Up)] / [▼(Down)] to make it to be setpoint of actual load compensation.

CON_35 Trq Balance Torque Balance quantity 0.0 ~ 100.0 % 50.0
6) Torque Bias Enable/Disable
Torque bias is enabled depending on the status of the multi-function terminal input set to ‘Torque bias enable’. But, if
‘Torque bias enable’ is not set and CON_32 is set to ‘Keypad’, the torque bias command set at CON_32 by the keypad, is
fed directly to the torque bias quantity regardless of the status of the terminal. Therefore, In order not to use the torque
bias command set at CON_33, CON_32 should be set to ‘None’ or the multi-function terminal input should be set to
‘Torque bias enable’ and then the terminal should be left open.

7) CON_34(Torque Bias F/F)
This is the torque bias quantity to compensate for the friction loss, which varies with the rotational direction of the
motor and added up to the torque bias quantity.
