● Acceleration: 32-bit (67 million computation units/second²)

 

General I/O

● 8-channel input

● 8-channel output

 

Extended I/O

● 40-input/24-output: Requires the I/O expansion board PICM-14064, all I/O signals of which have undergone optical isolation and operate at a 24V level.

 

High-speed position latching

● General inputs 1–4 are four-channel latched inputs, used for the X, Y, Z, and W axes (with an unisolated response speed of less than 0.1 μs; after optical isolation, the response speed is reduced to less than 25 μs).

 

Dedicated input (applicable to each axis)

● Main encoder inputs: A, A-, B, B-, I, I- (+/-12V or TTL)

● Positive and negative limit inputs—optocoupler included

● Zero-input—With optical isolation

● High-speed position latching input—optocoupler included

 

Dedicated output (applicable to each axis)

● 16-bit DAC analog instruction output

● Instruction pulses and direction outputs for stepper motors

● Servo enable output

● Alarm output

● High-speed position comparison output

 

Minimum servo update rate

● Axis 1–2: 125 μs

● 3~4 axes: 250 μs

 

Maximum feedback rate of the encoder

● 12 MHz

 

Maximum command rate of the stepper motor

● 3 MHz (full-step, half-step, or microstepping)

 

Power specifications
