5.7.3 Parameter Settings
Closed loop process control cannot be used unless P201 is first set to 001. Most of the parameters associated with closed loop process
control are shown in Figure 5.7.1. Other parameters which are also associated with closed loop process control are as follows:
P010
(only if P001 = 1, 4, 5, 7 or 9)
P061
(value = 012 or 013)
P220
Descriptions of all closed loop process control parameters are provided in section 6. For detailed information about PID operation, refer
