P-48 Standby Mode Timer
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.
P-49 PI Control Wake Up Error Level
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 User Output Relay Hysteresis
Sets the hysteresis level for P-19 to prevent the output relay chattering when close to the threshold.

Description
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.
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.
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.
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.
Description
P-45 is used
Analog input 1 signal level, readable in P00-01 is used for the setpoint.
Description
(Terminal 4) Signal level readable in P00-02.
(Terminal 6) Signal level readable in P00-01
Scaled as % of P-08
Scaled 0 – 1000 Volts = 0 – 100%
The value of Analog Input 2 is subtracted from Analog 1 to give a differential signal. The
value is limited to 0.
The larger of the two analog input values is always used for PI feedback.

The drive will trip and show the fault code  if the signal level falls below 3mA
The drive will ramp to stop if the signal level falls below 3mA
