DCS-100-A is microcontroller based drive with opto-isolated analogue output ±10V. It is used to drive third party servo amplifiers. DCS-100-A is suitable for retrofit of CNC machines which has robust servo power amplifiers for DC motors with analogue input.
Drive is based on 16-bit microcontroller with implemented PID control algorithm. As the feedback of DC motor position an incremental encoder with phase-shifted square signal (quadrature encoder) is used. Encoder interface enables 1x, 2x and 4x encoder resolution.
Adjustment of all parameters is performed by using the configuration software ServoTune3.
The input control interface enables control via opto-isolated lines in next modes:
- Encoder follower in 1x, 2x and 4x decoding, and
- Via analogue input within the range 0÷5 V with and without feedback.
- Built-in soft start function enables DC motor 1s after power on in order to decrease power surge on start.
There is an opto-isolated digital output on drive, named Track Error which is activated if preset value of tracking error offset is exceeded. That output can be used for activation of external circuit for DC motor emergency stop.
Use power supply 8÷24 VDC. Drive has reverse polarity protection.
- CNC machines retrofit
- Coordinate tables

ServoTune3 is configuration software for DC servo drives.
NOTE: For adjusting parameters od DCS-100-A use software version ServoTune3 Ver.3.09 or later.
