Chapter 15 PID Function (Built-in function)
15 - 25
16) _PIDxx_PWM (PWM output junction setting)
It sets the junction to which PWM output of ‘xx’ th loop is output. PWM output junction is valid
only between H’20 ~ H’3F. If any other value is entered, PWM output does not work.
17) _PIDxx_PWM_Prd (PWM Output cycle setting)
It sets the PWM output cycle of ‘xx’ th loop. The available scope is between 100 ~ 65,535 at the
unit of 0.1ms.
18) _PIDxx_SV_RAMP (SV ramp setting)
It sets the SV ramp value of ‘xx’ th loop. For more information about SV ramp of PV, refer to
15.2.3 PID control parameter setting. If it is set as 0, the function does not work.
19) _PIDxx_PV_Track (PV follow-up setting)
It sets the PV follow-up SV of ‘xx’ th loop. For more information about PV follow-up, refer to
15.2.3 PID control parameter setting. If it is set as 0, the function does not work.
20) _PIDxx_PV_MIN, _PIDxx_PV_MAX(Min. PV input, Max. PV input)
It sets the min./max. PV of ‘xx’ th loop.
21) _PIDxx_ALM_CODE (Warning code)
It indicates warning code if a warning occurs during ‘xx’ th loop run. The flag, as a dedicated
monitoring, is updated although a user directly enters it. For more information about warning
code, refer to 15.5.
