3.5.7 Parameter 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 Commissioning parameter
30 Factory
setting
P0970 = 1 Factory reset
0 disabled
1 Parameter reset
END
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.
