Instruction manual

** A function module is a part of the control that handles one of the machine’s facilities,
e.g. raising and lowering the transport roller. The control contains two function modules,
A and B.
Each function module has the following hardware:
–
one output (A or B), e.g. to control a solenoid valve
–
one input ( A or B), e.g. to connect a key
–
one output for an LED (A or B), e.g. displaying a switch status.
Each function module can be assigned various functions by the software. Each function
module has additional parameters, e.g. to activate counts or switch functions after the
thread is cut.
CAUTION:
Great care must be taken when changing parameter values,
as an incorrectly-set drive control may damage the
machine.
7.1.7 Master reset with the DA220C control
Any parameters that have been changed are restored to their pre-set values by a master
reset.
–
Turn off the main switch.
–
Press the “P” key, hold it down and turn on the main switch until “C.o.d.” appears.
–
Release the “P”key.
–
Enter the technician-level code. See section 7.1.4.
–
Press the “E” key: the parameter “1.0.0.” is displayed.
–
Press the “E” key: the value of parameter “1.0.0.” is displayed.
–
Set the value to 170.
–
Press the “P” key twice.
–
Turn off the main switch.
–
After a brief pause, turn the main switch on again. All parameters except 1.1.1.,
1.6.1., 1.7.0., 1.7.1. and 1.9.0. to 1.9.3., have been restored to their pre-set values.
CAUTION:
A few parameters, such as 1.7.0. (reference position),
1.7.1. (needle position) and 1.6.1. (direction of motor
rotation) are unaffected by a master reset.
After a master reset all machine-specific parameters
must be readjusted in accordance with the parameter
sheet. See section 7.1.6.
