Parameter Settings for the Fully-closed System
This section describes the user parameters that must be set when using a DeviceNet Unit.
Overflow Level
For information on parameter contents, refer to the OMNUC W-series Servomotors/Servo
Drivers User's Manual (I531-E1- ). The default setting is made to minimize the chance of
the motor going out of control due to wiring errors or other causes. After performing a trial
operation at a low speed, change the setting to a higher value if necessary.
Fully-closed Encoder
Set the method for using the fully-closed encoder.
Pn002.3 Fully-closed Encoder Usage Method
The setting details are as follows:
Parameter Setting
Pn002.3
(Default setting)
Setting the Pn002.3 to 0 enables the operation with the normal semi-closed specifications.
When changes have been made to this parameter, turn OFF the power once. The set value
will become effective when the power is turned ON again.
Number of Fully-closed Encoder Pulses
Set the number of fully-closed encoder pulses for each motor rotation.
When the number of fully-closed encoder pulses per motor rotation is not an integer, set the
closest integer.
Error will occur in the speed monitor for position loop gain, feed forward, and command
pulse, but no position displacement will occur. Set the number of pulses with a multiplica-
tion factor of 1.
Pn206 Number of Fully-closed
Encoder Pulses
Note Set the Pn206 to 513 or more.
When changes have been made to this parameter, turn OFF the power once. The set value
will become effective when the power is turned ON again.
