GR (Gear Ratio)

[Motion]

DESCRIPTION:

GR specifies the Gear Ratio for the slave axis in electronic gearing mode. The master axis for the

SMC–4000

is specified with the

GA (Master Axis for Gearing)

command. Gear ratio may range between

+/-127.9999. The slave axis will be geared to the actual position of the master. The master can go in both
directions. GR 0 disables gearing. If a limit switch is hit during gearing, then gearing is automatically
disabled.

ARGUMENTS: GR n

where

n is a signed number.

0 disables gearing

USAGE:

OPERAND USAGE:

_GRn contains the value of the gear ratio where n is an axis letter.

EXAMPLES:

Note: The gear ratio value entered has a resolution of 1/16. This means that a gear ratio of 1.35 will be

stored as 1.349996. To check a given ratio, multiply the fractional portion by 65535 (0.4 × 65535
= 26214.4). Only the integer portion is stored, so the actual fraction is 26214/65535.
