1.2 Key Features and Functions
(1) Input/output of control signals by means of RS485 serial communication (conforming to the Modbus
protocol)
(2) 64 positioning points
(3) Variable zone output boundaries
Before, zone output boundaries were set by parameters and therefore fixed. For greater convenience, this
product permits setting of zone output boundaries in the position table. (Available in the position number
specification mode only)
Set desired boundaries to prevent contact with peripheral equipment, shorten the tact time, etc.
(4) Different acceleration and deceleration settings (Available in the position number specification mode only)
Acceleration and deceleration can be set differently in the position table.
In situations where shock and vibration upon stopping must be minimized depending on the material or
shape of the load, you can decrease only the deceleration to allow the actuator to stop along a gradual
deceleration curve.
(5) Limitation of moving speed during adjustment by trial operation
During adjustment by trial operation, the moving speed of the actuator can be limited to ensure safety.
(6) Power-saving measure
In general, pulse motors generate greater holding current than AC servo motors in a standstill state.
Accordingly, we provide a power-saving mode to conserve electricity in situations where the actuator stands
by for a long period.
