• Manufacturer: Omron

Specifications of R88M-W75030T-S1

• Lead Free Status / Rohs Status: Lead free / RoHS Compliant
• Other names: R88MW75030TS1

Operation
• Sets the feed-forward compensation value during positioning.
• When performing feed-forward compensation, the effective Servo gain rises, improving response.
• Use to shorten positioning time.
Note Setting a high value may result in machine vibration. Set the feed-forward amount for general
• Sets the feed-forward primary (lag) command filter during position control.
• If the positioning completed signal is interrupted (i.e., repeatedly turns ON and OFF) because of
●
Setting Explanation
• Sets the speed control loop switching function from PI control to P control.
• Normally, using the speed loop gain and the position loop gain set by means of the auto-tuning
• When PI control is always being used, switching to P control may help if the Servomotor speed
• If the output torque is saturated during acceleration and deceleration, set speed control to 0
• If the speed control overshoots or undershoots without the output torque being saturated during
