1
If a load generating large rush current is used, thyristor break-down may occur when no soft-start time is appropriately set.
Also in Zero-cross control, no rush current can be suppressed even if the soft-start time is set.
2
If the protection function for control of primary side of a transformer is enabled, soft-start function is always operated for 0.1
second regardless of setting of soft-start time (U) at 0.0 seconds.
3
Output limiter high value must be equal or higher than Output limiter low.
4
These function can not be used together.
5
Base-up set value will not exceed the Output limiter high.
6
The Output mode setting is invalid when the Control method is Zero-cross control.
7
These parameters cannot be set when the Heater break alarm, Current limiter, Constant current control and Protection
function for control of primary side of a transformer functions are not provided. If the rated current of thyristor differs from that
maximum load current flowing through the heater when the Constant current control is selected, compensate for the difference
by setting the gradient. Set the gradient so that the maximum heater load current will flow through the heater at an input signal
of 100 % from the controller. (Refer to P. 19)
