3.5.7Parameter reset to the factory setting

The factory setting is a defined initial state of all of the drive inverter parameters. The drive inverters are shipped from the factory in this state. The drive inverters have the following default settings:

Control via the digital inputs

a)ON/OFF via DIN1

b)Direction of rotation reversal via DIN2

c)Fault acknowledgement via DIN3

Setpoint input via analog input

Signal output via the digital output

a)Fault active via DOUT 1

Actual frequency via the analog output

The basic V/f characteristic is the control mode (P1300 = 0) Induction motor (P0300 = 1)

When appropriately connected-up and with the appropriate motor – drive inverter combination, MICROMASTER drive inverters are ready to run when shipped from the factory without requiring any additional parameterization.

You can re-establish the initial state at any time by carrying-out a parameter reset to the factory setting. This undoes all of the parameter changes which were made since the drive inverter was supplied. This value is designated as "Def" in the parameter list.

Reset to the factory setting

START

P0010=30

P0970 = 1

END

Commissioning parameter		0
30	Factory setting
Factory reset		0
0	disabled
1	Parameter reset

The drive inverter carries-out a parameter reset (duration, approx. 10 s) and then automatically exits the reset menu and sets:

P0970 = 0 : disabled

P0010 = 0 : ready

NOTE

When resetting the parameters to the factory setting, the communications memory is re-initialized. This means that communications via USS as well as also via the CB board are interrupted for the time it takes to make the reset:

The connected PLC (e.g. SIMATIC S7) goes into stop

The STARTER start-up program buffers the communications failure

For the DriveMonitor start-up program, "NC" (not connected) or "drive busy" is displayed.

The "busy" text is displayed at the BOP operator panel

After reset has been completed, for the start-up programs STARTER and DriveMonitor or the BOP operator panel, communications are automatically re- established.
