Save to EEPROM

By storing the parameterization in the non-volatile memory (EEPROM) of the

frequency inverter, the settings are retained even after a power failure.

Note

A list of all parameters of the SINAMICS G120P drive can be found in the list

Operation

Make sure that the moving drive does not pose a danger to persons or

system sections.

Take suitable measures to prevent the drive from exceeding technical or

WARNING

mechanical limits.

After the power supply of the SINAMICS drive has been activated and the timer

(DTC) parameter has been set, the pump drive is controlled by time.

Note that the motor data is determined after the SINAMICS G120P drive is

switched on for the first time. (for the setting p1900 = 2, see

Pump with SINAMICS G120P

Entry-ID: 109759888,

V1.0.1,

Parameters

p8412[0]

Set the parameter p8412[0] (switch-off time hour) to the

value 21 (21.xx clock).

p8412[1]

Leave the parameter p8412[1] (switch-off time minute) at the

value 0 (21.00 h).

p8409

Finish the parameterization of the DTC by setting the

parameter p8409 (DTC activation) to the value 1.

p0840

Connect parameter p0840 (ON/OFF) to the output of the

DTC (parameter r8413[0]). This defines the output of the

DTC as the signal source for activating the drive.

p1000

Set parameter p1000 (speed reference selection) to value 3

(speed fixed reference).

p1001

In parameter p1001 (fixed speed setpoint 1), enter the

desired speed of the pump in revolutions per minute.

Parameters

p0971

Set the value of parameter p0971 (Save parameter) to 1.

Wait until parameter p0971 displays the value 0 again.
