Servo Drive Settings - Omron NY532-1500 User Manual

5 Motion Control Parameters
Modulo Maximum Position and Modulo Minimum Position Setting
Values
The settings of these parameters are enabled when the Count Mode is set to Rotary Mode. Set the
upper and lower limits of the ring counter.
Precautions for Correct Use Precautions for Correct Use
• If 0 is not included between the upper and lower limits of the ring counter, an error occurs
when the MC_MoveZeroPosition (High-speed Home) instruction is executed.
• When you perform absolute positioning with a MC_MoveAbsolute or MC_Move instruction,
make sure that the target position is within the range of the ring counter. An error occurs if the
target position is not within the range of the ring counter. If the Direction input variable to the
instruction is set to No direction specified, you can set a target position that is not within the
range of the ring counter. If that occurs, relative positioning is performed using the difference
between the target position and the command current position as the target distance.
• When you make a change in the position count settings, there are some differences between
the physical position of the machine and the command current position of the MC Function
Module. Therefore, if you made a change in the position count settings, execute the Home
instruction to define the home again.
Encoder Type
Set the type of encoder to use for feedback input.
Set the encoder type to 1 (absolute encoder (ABS)) when you use any of the following.
• When an OMRON 1S-series Servomotor/Servo Drive is used
• When an OMRON G5-series Servomotor/Servo Drive with an absolute encoder is used
• When an OMRON G5-series Servomotor/Servo Drive with an absolute external scale for fully-closed
control is used
• When an OMRON G5-series Linear Motor Type Servomotor/Servo Drive with built-in EtherCAT com-
munications is used with an absolute external scale
