How do I calculate the control accuracy of the linear motor?
1. Check the values of the following drive parameters: P1.044, P1.045, and PM0.4.
2. If P1.044 = 250, P1.045 = 1, and PM0.4 = 4, then 1 PUU (Pulse Unit) equals 1 pulse.
3. Calculate using the following formula:
4nm/pulse (PM.04) x 250 (P1.044) pulse/rev = 1000nm = 1μm
Hence, under the condition that 1 PUU equals 1 pulse, the control accuracy is 1μm.
