PLZ-4WH
Response Speed
The PLZ-4WH operates by detecting the input current or voltage and controlling it through
negative feedback. You can ensure stable operation by reducing the response speed.
The response speed can be specified in CV mode and CR mode.
Make the wiring as short as possible, and twist it. Then, reduce the slew rate or decrease the
response speed to ensure that the voltage resulting from inductance remains within the PLZ-
4WH’s minimum operating voltage and maximum input voltage ranges.
If the load wiring is long or if there are large loops in the load wiring, voltage drops leading to
distortions in the current waveform may occur. In addition, the voltage may exceed the PLZ-
4WH’s maximum input voltage, causing damage to the PLZ-4WH. Be careful when you are
performing switching operations with large currents (when the slew rate is high and when you
are operating the PLZ-4WH in parallel).
During DC operation, it is possible for the phase lag of the current to result in unstable PLZ-
4WH control and oscillation.

CC and CR mode response speeds
There are four response speeds in CC mode and CR mode:
1/1: This is the normal response speed (the factory default setting).
1/2: This is 1/2 the normal response speed (twice as slow).
1/5: This is 1/5 the normal response speed (five times as slow).
1/10: This is 1/10 the normal response speed (10 times as slow; equivalent to the PLZ-
3WH series).
The settings other than 1/1 result in a slow response speed, so this has an effect on features
such as the soft start, the slew rate, and the load on and load off rise and fall times. The slew
rate also has an effect on switching operation.
To set the response speed of negative feedback, from the menu, select “1. Setup” > “5.
Response” > “CC/CR.”

CV mode response speed
There are five response speeds in CV mode:
100: This is 100 times the normal response speed (100 times as fast; equivalent to the
PLZ-3WH series).
10:
This is 10 times the normal response speed (10 times as fast).
1:
This is the normal response speed.
1/10: This is 1/10 the normal response speed (10 times as slow; factory default setting).
1/100: This is 1/100 the normal response speed (100 times as slow).
To set the response speed of negative feedback, from the menu, select “1. Setup” > “5.
Response” > “CV.”
