AYK550-UH User's Manual
Group 42: External PID
This group defines the parameters used for the second PID controller (PID2) of
AYK550
The operation of parameters 4201...4221 is analogous with Process PID set 1
(PID1) parameters 4001...4021.
Code Description
4201
See 4001 ...4021
...
4221
4228 ACTIVATE
Defines the source for enabling the external PID function.
• Requires 4230
0 =
– Disables external PID control.
NOT SEL
1 =
1 – Defines digital input
DI
• Activating the digital input enables external PID control.
• De-activating the digital input disables external PID control.
2...6 =
2...
6 – Defines digital input
DI
DI
• See
1 above.
DI
7 =
– Defines the start command as the control for enabling external PID control.
DRIVE RUN
• Activating the start command (drive is running) enables external PID control.
8 =
– Defines the power-on as the control for enabling external PID control.
ON
• Activating power to the drive enables external PID control.
9...12 =
1...4 – Defines the Timer as the control for enabling external PID control (Timer active enables
TIMER
external PID control).
• See parameter Group 36: Timer Functions.
-1 =
1(
) – Defines an inverted digital input
DI
INV
• Activating the digital input disables external PID control.
• De-activating the digital input enables external PID control.
-2...-6 =
2(
)...
DI
INV
• See
1(
) above.
DI
INV
4229 OFFSET
Defines the offset for the PID output.
• When PID is activated, output starts from this value.
• When PID is deactivated, output resets to this value.
• Parameter is not active when 4230
4230 TRIM MODE
Selects the type of trim, if any. Using the trim it is possible to combine a corrective factor to the drive reference.
0 =
– Disables the trim function.
NOT SEL
1 =
PROPORTIONAL
2 =
– Adds a trim factor based on the control loop's maximum limit.
DIRECT
4231 TRIM SCALE
Defines the multiplier (as a percent, plus or minus) used in the trim mode.
