Be short-curcuited between ST and SN terminal. when the stop gain or the stop bias is not used.
1. Setting items by key operation
(1) Input signal level ( initial value : 5V )
When the power source is turned on with the DIP SW1 and SW3 turned on and the DIP SW2
turned off, the input voltage free mode is set, by which the input signal voltage level ( Vmax = 0.5
~ 8V ) is validated by the key operation.
(2) Non-linearity compensation ( initial setting : Lineare line )
If the transmission torque (%) of clutch / brake at excitation current of 20%, 40%, 80% has been
set, the non-linearity compensation is executed by 5-stage polygonal line approximation method.
(3) Inversion of remote input [RC] logic
Under the initial condition, the power amplifire output is validated when the input is turned on.
(4) Stop gain ( initial value : 100%)
(5) Stop bias ( initial value : 0%)
(6) Stop timer ( initial value : 10 sec)
(7) Aux.power output limit time ( initial value : 10 sec)
• The unit can be generally used as a power amplifire at the initial value (value at time of factory shippment ).
It is recommended to set the non-linearity compensation in accordance with the procedure shown in page
13.
• It is desirable to execute the setting of above items (4) ~ (7) at the tension control unit side. It will be con-
venient to set the power anplifire side timer, to as longer time as possible.
