6.6.1 Restoring parameters to factory settings
When you reset parameters to the factory settings, all stored parameters and data
will be lost. Once the device has been reset to its factory settings, it must be
commissioned again.
● Make a copy of the working settings before you reset the variable speed drive
The communication settings and the settings of the motor standard (IEC/NEMA)
are retained after resetting.
Proceed as follows to reset the variable speed drive to its factory settings:
1. Go online with STARTER.
2. Click the button.
1. Select Options > Parameter settings > Reset drive to factory settings.
2. Confirm with OK.

6.6.2 Setting the PID controller
Setting the PID controller
If the PID controller is activated, the set ramp times are bypassed in p1120 and
p1121 (applies only to FW < V4.7 SP3).
● Therefore, define the following settings for smoothing times, ramp times and
controller.
p2200 1 Setting of the signal source for switching the technology
controller on/off.
p2253 r2224 Technology controller setpoint
● r755.0: Analog setpoint (AI0)
● r2224: Technology controller fixed value
● r2050.1: Setpoint fieldbus
p2257 30s * Technology controller setpoint ramp-up time
p2258 30s * Technology controller setpoint ramp-down time
p2264 r755.1 Technology controller actual value
r755.1: Analog actual value (AI1)
p2265 10s * Technology controller actual value filter time constant
