Setting examples of the parameters are shown in the table below:
Note: Select “enabled” (=1) in bit 9 “Override Selection” of fixed motion parameter 17.
Rated speed and number of feedback pulses per rotation are automatically
transmitted to the MP940 at power ON as data on the motor connected to
the SGDH.
Pulse counting mode selection: A/B format, fixed at quadrature
Examples of Parameter Setting
If the Speed Reference Selection is set to “0”
a.) When “pulses” is designated as the unit
When operating with fast feed speed = 1500rpm, approach speed =
300rpm, creep speed = 150rpm in the parameter settings
• OWC00A = 300(rpm)×2048×4(ppr)÷1000 = 2457(=2457000ppm)
• OWC00B = 150(rpm)×2048×4(ppr)÷1000 = 1228(=2457000ppm)
• OWC015 = --- --- --- (disabled)
• OLC022 = 1500(rpm)×2048×4(ppr)÷1000 = 12288(=12288000ppm)
• OWC02C = 10000(100%)
b.) When “mm” is designated as the unit
