Description
0
Direct Operation
Use this mode if when the feedback signal drops, the motor speed should increase. When the
drive restarts following standby, the PID controller will restart from zero.
1
Inverse Operation
Use this mode if when the feedback signal drops, the motor speed should decrease. When the
drive restarts following standby, the PID controller will restart from zero.
2
Direct Operation
Use this mode if when the feedback signal drops, the motor speed should increase. When the
drive restarts following standby, the PID controller will restart from maximum.
3
Inverse Operation
Use this mode if when the feedback signal drops, the motor speed should decrease. When the
drive restarts following standby, the PID controller will restart from maximum.

Analog 1 – Analog 2
The value of Analog Input 2 is subtracted from Analog 1 to give a differential signal. The
value is limited to 0.
5
Largest (Analog 1, Analog 2)
The larger of the two analog input values is always used for PI feedback.

When standby mode is enabled by setting P-48 > 0.0, the drive will enter standby following a period of operating at minimum speed
(P-02) for the time set in P-48. When in Standby Mode, the drive display shows , and the output to the motor is disabled.

%
When the drive is operating in PI Control Mode (P-12 = 5 or 6), and Standby Mode is enabled (P-48 > 0.0), P-49 can be used to define
the PI Error Level (E.g. difference between the setpoint and feedback) required before the drive restarts after entering Standby
Mode. This allows the drive to ignore small feedback errors and remain in Standby mode until the feedback drops sufficiently.
P-50

Sets the hysteresis level for P-19 to prevent the output relay chattering when close to the threshold.
