PID with continuous parameter calculation
PID with parameter calculation on command
PID with calculation of parameters at power-on once only
P86 - Setpoint deviation for Pretune activation Loop 1 (Address ModBus 2086)
P112 - Setpoint deviation for Pretune activation Loop 2 (Address ModBus 2112)
P138 - Setpoint deviation for Pretune activation Loop 3 (Address ModBus 2138)
Threshold for starting the oscillation necessary for calculating PID parameters with the Pretune function
0-10000 [digit]
0.0-1000.0° with thermocouple.
Default:
30.0.
P87 - Proportional band Loop 1 (Address ModBus 2087)
P113 - Proportional band Loop 2 (Address ModBus 2113)
P139 - Proportional band Loop 3 (Address ModBus 2139)
Proportional band for PID process control (process inertia)
If Proportional band = 0 and Integral Time = 0, the regulation becomes type ON / OFF
1 ÷ 10000 [digit]
0.1 ÷ 1000.0° with thermocouple.
Default:
0
P88 - Integral time Loop 1 (Address ModBus 2088)
P114 - Integral time Loop 2 (Address ModBus 2114)
P140 - Integral time Loop 3 (Address ModBus 2140)
Integral time for PID process control (duration of process inertia)
0.0 ÷ 2000.0 sec. (0.0 = disabled),
Default:
0.0
P89 - Derivative time Loop 1 (Address ModBus 2089)
P115 - Derivative time Loop 2 (Address ModBus 2115)
P141 - Derivative time Loop 3 (Address ModBus 2141)
Derivative time for PID process control (usually ¼ of the integral time)
0.0 ÷ 1000.0 sec. (0.0 = disabled),
Default:
0
