WARNING
¾
For series commissioning, all of the communication interfaces as well as also
the digital and analog interfaces are re-initialized. This results in a brief
communications failure or causes the digital outputs to switch.
¾ Potentially hazardous loads must be carefully secured before starting a series
commissioning.
¾ Potentially hazardous loads can be secured as follows before starting series
commissioning:
♦ Lower the load to the floor, or
♦ Clamp the load using the motor holding brake
(Caution: During series commissioning, MICROMASTER must be prevented
from controlling the motor holding brake).
¾ If the motor holding brake (refer to Section 3.14) is controlled by the
MICROMASTER, then series commissioning may not be carried-out for
potentially hazardous loads (e.g. suspended loads for crane applications).
3.5.9 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:
¾
Control via the digital inputs
a) ON/OFF via DIN1
b) Direction of rotation reversal via DIN2
c) Fault acknowledgement via DIN3
¾ Setpoint input via analog input 1
¾ Signal output via the digital outputs
a) Fault active via DOUT 1
b) Warning active via DOUT 2
¾ Actual frequency via the analog output
¾ The basic V/f characteristic is the control mode (P1300 = 0)
¾ 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.
