RW Real

1074 PID Fdbk AnlgLo

PID Feedback Analog Low

When an analog input is selected for PID Feedback this sets low value of scaling.

Units:

Default:

Min/Max:

0.00

RW Real

1075 PID FBLoss SpSel

PID Feedback Loss Speed Select

When an analog input is selected for PID Feedback, P1079 [PID Output Sel] is set to

Speed Excl/Speed Trim, and an analog signal loss is detected, sets speed to this source.

Analog signal loss occurs when the signal falls below 2V (0…10V signal) or below 4 mA

(4…20 mA signal).

1076 PID FBLoss TqSel

PID Feedback Loss Torque Select

When an analog input is selected for PID Feedback, P1079 [PID Output Sel] is set to

option 1 “Speed Excl,” 2 “Speed Trim,” 3 “Torque Excl,” or 4 “Torque Trim” and an analog

signal loss is detected, sets torque to this source.

Default:

RW 32-bit

Integer

1077 PID Fdbk

PID Feedback

Provides an internal fixed value for PID Feedback when P1072 [PID Fdbk Sel] is set to this

parameter.

RW Real

1079 PID Output Sel

PID Output Select

Selects the target for the PID Output.

“Not Used” (0) – PID output is not applied to any speed reference.

“Speed Excl” (1) – PID output is only reference applied to speed reference.

“Speed Trim” (2) – PID output is applied to speed reference as a trim value.

“Torque Excl” (3) – PID output is only reference applied to torque reference.

“Torque Trim” (4) – PID output is applied to torque reference as a trim value.

“Volt Excl” (5) – PID output is only reference applied to voltage reference.

“Volt Trim” (6) – PID output is applied to voltage reference as a trim value.

Default:

Options:

2 = “Speed Trim”

0 = “Not Used”

1 = “Speed Excl”

2 = “Speed Trim”

3 = “Torque Excl”

4 = “Torque Trim”

5 = “Volt Excl”

6 = “Volt Trim”
