Software Reset of the Absolute Encoder
This operation is used to set the present position for a specific axis or all axes
using an absolute encoder tentatively to “0.”
Note This procedure is only supported for the CV500-MC221/421 and C200H-
MC221.
This operation is used to set the offset value to the system parameters. This op-
eration is used when incrementing the mechanical origin established using the
initial setting procedure. With a software reset, it is not necessary to perform set-
up at the Servodriver as it is when performing initial setting.
As with initial setting, once the mechanical origin is established, it will never be
necessary to perform it again. As a safety precaution, this function can be pro-
tected by setting DIP switch pin 1 on the MC Unit to ON. In this protected state, if
an attempt to perform this function is made, an error will be generated.
This procedure has the following restriction:
A software reset cannot be performed if the present position has an absolute val-
ue exceeding 32,767 pulses. In this case, if this procedure is attempted, an error
will be generated.
Note
1. This operation is used when performing incrementing after permanently
setting the absolute value to “0” in the absolute encoder initial settings.
2. Before performing this procedure, it is necessary to set DIP switch pin 1 on
the MC Unit to OFF.
If “6.ABS SOFT RSET” is selected in EXTENSION mode with DIP switch pin 1
ON, the following display will appear:
TURN OFF
DIP SW No.1 AND
THEN PROCEED.
Press the CLR Key to return to the EXTENSION mode menu. After releasing
memory protection by selecting “4.MEM PROTECT,” re-attempt the procedure.
Procedure
Use the following procedure to perform a software reset for an absolute encoder.
Note After completion of a software reset, as a safety precaution, perform backup for
the system parameters using MC Support Software.
