Chapter 7. PARAMETER SETUP
0 : 5S output (current proportional SP output)
1 : 5G output (current proportional control output)
2 : 6D output (voltage time proportional control output) system A
3 : 6D output (voltage time proportional control output) system B
4 : 8D output (open collector time proportional control output) system A
5 : 8D output (open collector time proportional control output) system B
[Description:]
The difference between system A and system Bis in the output system of
ON-OFF control and auto-tuning.
System A: Output ON-OFF is performed regardless of time proportional
output cycles and output limits.
System B: The output limit upper limit value is output instead of on and the
output limit lower value is output instead of off according to time
proportional output cycles.
