USAGE ♦ ♦ ♦
SYNTAX xxQRnn1,nn2 or xxQR?
PARAMETERS
Description xx [ int ] - axis number
nn1 [ int ] - delay period
nn2 [float ] - motor current reduction percentage
Range xx - 1 to MAX AXES
nn1 - 0 to 60000
nn2 - 0 to 100
Units xx - none
nn1 - milliseconds
nn2 - percent of max. motor current
Defaults xx missing: error 37, AXIS NUMBER MISSING
missing parameter: error 38, COMMAND PARAMETER MISSING
out of range: error 9, AXIS NUMBER OUT OF RANGE
DESCRIPTION This command automatically reduces the specified step motor’s current (i.e.,
torque) output to the requested percentage nn2 after motion has stopped and the
specified time nn1 has expired. The purpose of this command is to help reduce
the motor heating typically generated by stepper motors. If xx
is equal to 0, the
torque reduction parameters get applied to all axes.
Note:
This command does not affect DC servo motors and pulse stepper motors.
Note:
Time parameter nn1 is only effective for ESP300 motion controller
RETURNS If “?” sign is issued along with command, the controller returns the torque
reduction settings for the specified axis.
REL. COMMANDS QM - set motor type
QI - et motor current
EXAMPLE 2QR1000,50 | reduce motor #2 torque to 50%, 1000 msec after a move
done
2QR? | query motor #2 torque reduction settings
1000,50 | controller returns 1000 msec and 50%
