DE – Deceleration
Changes decel setting of drive. Also allows you to request present decel setting.
Range is 1 – 3000.
Affects: FL, FS, FP, SH
See also: AC
Example:
You send
Drive sends
DE125 nothing
DE DE=125
DI – Distance/Position
Sets or requests move distance, in steps. The sign of DI indicates move direction.
Affects: FL, FS, FP, SH, CJ
See also: AC, DE, VE
Example:
You send
Drive sends Notes
DI20000 nothing cw direction
DI-20000 nothing ccw direction
DI DI=-20000
DL – Define Limits
Sets limits to normally open (1), normally closed (2) or not used (3).
Affects: FL, FS, FP, SH, WI (jogging)
Example:
You send
Drive sends Notes
DL1 nothing limits are normally open
DL3 nothing limits are not used
ED – Encoder Dead Band
On drives that have the encoder feedback option, this defines the size of the “in position” region. If
static position maintenance is enabled and a motor at rest deviates from this zone, automatic correc-
tion occurs. If “end of move correction” is turned on, and the motor is outside the dead band at the end
of a feed to length or feed to position move, automatic error correction occurs. The size is in encoder
counts.
Example:
You send
Drive sends Notes
ED50 nothing dead band is 50 encoder counts
ED ED=50
EF – Encoder Function
On drives supporting encoder feedback, the EF command tells the drive what kind of position mainte-
nance you want. Static position maintenance watches the encoder while the motor is at rest. If an
external force moves the motor out of position, the drive tries to return it to within the dead band. “End
of move correction” checks the encoder position after a feed to length or feed to position move. If the
