EG - Electronic Gearing

Compatibility: All drives

Affects: Command Mode 7, FE and HW commands

See also: CM, ER, FE and HW commands.

SRV-AC5, SRV-DC7

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.

STP-10-Q, ITM-23Q

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

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
