Position
system |
Command pulses |
Positioning pulse-train output by differential driver |
Position
command range |
-134,217,728 to +134,217,727 pulse |
Command coordinate |
Relative coordinate command
|
Reference range atcontinuous feed |
Unlimited (linear movement counter overflows if movement goes beyond the end, and rotation counter resets to zero at every 360 degrees of rotaion)
|
Position override |
Possible only in positioning control |
Speed
control |
Speed range |
0.1pps to 6.5Mpps (x0.1 to x100) (Encoder counting frequency limited to 4MHz max, in x4 mode.) |
Constant control oflinear speed |
2-axes circular, linear interpolation of : 2 control
3-axes linear interpolation of : 3 control
4-axes linear interpolation of : 3 control |
Speed override |
(1)Available in any constant-speed oparation
(2)Availablel only with positioning, linear interpolation, and continuous feeds when acceleration and/or deceleration involved. |
Acceleration
/deceleration
control |
Automatic acceleration/ deceleration
system |
(1) Positioning and linear interpolation: Linear acceleration/deceleration, S-curve acceleration/deceleration,
and partial s-curve acceleration/deceleration
Automatic damping function available in case of abrupt acceleration reversalTriangular drive peak prevention function available
Asymmetrically sloped acceleration / deceleration possible |
(2) For circular interpolation: Automatic acceleration / deceleration possible
(constant-speed control not possible)
Aacceleration and deceleration blocks to be used for circular interpolation at constant movement.

Inputs for encoder or pulsa |
Each axis has a common input terminal for the encoder and pulsar input signal
|
Not available |
Backlash compensation |
Compensated for at every turn of the direction of movement by correction pulse. |
Slip compensation |
Compensated immediately before moving regardless of the direction (good for positioning system only) |
Positioning-control-start (PCS) signal |
Starts positioning by PCS signal during continuous
feed ( positioning system only) |
Altemationgly shared with OLS of B axis. |
