6.7 Writing Linear Servomotor Parameters
If you connect a linear encoder to the SERVOPACK without going through a Serial Con-
verter Unit, you must use the SigmaWin+ to write the motor parameters to the linear
encoder. The motor parameters contain the information that is required by the SERVO-
PACK to operate the Linear Servomotor.
You can download the motor parameters from our web site (http://www.e-mecha-
tronics.com/).
WARNING!
Check the Servomotor and linear encoder information before you
write the motor parameters.
If you do not write the correct motor parameters, the Servomotor may run
out of control or burning may occur, possibly resulting in equipment
damage or fire.

Serial number information is not included in the motor parameters. You
cannot use the monitor functions of the SERVOPACK to monitor the
serial number. If you attempt to monitor the serial number, ********** will
be displayed.
n If the encoder parameters are not written to the linear encoder, an A.CA0 alarm
(Encoder Parameter Error) will occur. Consult the manufacturer of the linear encoder.
n If the motor parameters are not written to the linear encoder, an A.CA0 alarm
(Encoder Parameter Error) will not occur, but the following alarms will occur.
– A.040 (Parameter Setting Error)
– A.041 (Encoder Output Pulse Setting Error)
– A.050 (Combination Error)
– A.051 (Unsupported Device Alarm)
– A.550 (Maximum Speed Setting Error)
– A.710 (Instantaneous Overload)
– A.720 (Continuous Overload)
– A.C90 (Encoder Communications Error)
The following table lists the tools that you can use to write the parameters to the Linear
Servomotor and the applicable tool functions.
