|
DIR.-A direction operation command pulse signal (pulse input when 1-pulse input mode) Pulse width 2 μs min., rise/fall time 2 μs max. (Negative logic pulse input) |
||||
|
DIR.-B direction operation command pulse signal (operation direction switch input when 1-pulse input mode) Pulse width 2 μs min., rise/fall time 2 μs max. (Negative logic pulse input) |

|
Input when protective function is activated to clear the alarm status. | ||||
|
When the photocoupler is ON, output current to the rack and pinion motor is turned OFF. When the photocoupler is OFF, the current is supplied to the rack and pinion motor. |
||||
|
When the photocoupler ON, the resolution is 10 times the resolution at power on. When the photocoupler is OFF, the resolution is the resolution at power on. |
||||
| Output Signals | Output Mode | Photocoupler and Open-collector output External use condition 30 VDC max, 15 mA max (Positioning completion, Alarm) Transistor and Open-collector output External use condition 30 VDC max, 15 mA max (Timing, Feedback pulse phase A and B) Line driver output 26C31 equivalent (Timing, Feedback pulse phase A and B) |
|||
|
1-pulse outputs each time the rack moves the value shown in Table 1. (Photocoupler: ON) Available in 500 Hz max. in maximum speed input pulse frequency. |
||||
|
Outputs when the protective function is activated. (Photocoupler: OFF) Alarm outputs (Blinking red LED), while at the same time, the rack and pinion motor comes to a coasting stop. |
||||
|
Outputs on positioning completion. (Photocoupler: ON) Output is within ±0.05 mm of the command position at a pulse speed of 500 Hz max. |
||||
|
Outputs at the resolution when the driver is powered on. The phase difference between phase A and phase B is 90˚ in electrical angle. There is a time lag of up to 1 ms relative to the actual motion of the rack and pinion motor. Use to confirm the stop position. |

Rack Permissible Rotational Torque (Moment)
The rotational torque applied to the rack should be less than the value shown in the table below.
| Rack and Pinion Motor Product Name | Rack Permissible Rotational Torque (Moment) |
|---|---|
| LAS2B(F) | 0.3 N·m max. |
| LAS4B (F) | 0.5 N·m max. |
- Be sure to keep rotational torque below the permissible value. If too much rotational torque is applied, the abrasion of rack bushings will be sped up.
Repetitive Positioning Accuracy (Reference value)
The graph on the figure below shows the actual measurement value at maximum transportable mass. Varies depending on the load, driving conditions, and mounting direction.
