Host Command Reference
EG - Electronic Gearing
Compatibility: All drives
Affects:
Command Mode 7, FE and HW commands
See also: CM, ER, FE and HW commands.
BLu, SV
Sets or requests the pulses per revolution for electronic gearing. For example, with an EG value of 20000 the
servo drive will require 20000 pulses from the master pulse source to move the servo motor 1 revolution.
STAC6, ST-Q/Si, ST-S, STM
Sets or requests the desired step/microstep resolution of the step motor.
Command Details:
Structure EG{Parameter #1}
Type BUFFERED
Usage READ/WRITE
Non-Volatile YES
Register Access “R” (034)
Note: With servo drives the EG command is equal to the
“R” register. With stepper drives the EG command is equal
to twice the “R” register.
Parameter #1 Servo = electronic gearing ratio
Stepper = step resolution
- units Servo = counts/rev
Stepper = steps/rev
- range Servo = 200 - 32000
Stepper = 200 - 51200
Examples:
Command Drive sends Notes
EG20000 - Set electronic gearing resolution in servo drive to 20000 pulses/rev
EG EG=20000
RLR
RLR=20000 “R” register matches the EG setting in a servo drive
EG36000 - Set microstep resolution to 36000 steps/rev in a stepper drive
EG EG=36000
RLR
RLR=18000 “R” register contains 1/2 the EG setting in a stepper drive, or 18000
steps/rev
