DCS-100-A v.3 is microcontroller based drive with opto-isolated analog output ±10V. It is used to drive third party servo amplifiers. The servo driver DCS-100-A converts the step/dir digital control signals into a +/-10V analog control signal and it is suitable for upgrading (retrofit) of CNC machines which has robust servo power amplifiers for AC or DC motors with analog 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:
- STEP/DIR/ENABLE,
- CW/CCW/ENABLE,
- Encoder follower in 1x, 2x and 4x decoding, and
- Via analog 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 servo motor emergency stop.
Use power supply 8–24 VDC. Drive has reverse polarity protection.
| SAFETY PRECAUTION |
|
When working with the DCS-100-A servo drive, there are dangers and risks that can lead to damage to the equipment, as well as injuries to persons in the environment. |
| During the installation procedure of the DCS-100-A servo drive, it is necessary to have a high level of knowledge in the field of electronics, computer technology and mechanics. It is also necessary to observe safety measures when working with high voltage and mechanical hazards caused by working with heavy and dangerous machines. |
| Supply voltages over 50 VDC can be danger of death. |
| Drive should not be used in places where, in case of failure, people safety is in danger, financial losses are big, or there exist other losses. During drive operation should be used all required precautious. |
| Does not exclude the possibility that this document contains errors. In addition the manufacturer assumes no responsibility for any damage caused by the use of this drive, which has occurred as a result of compliance or non-compliance with this instruction manual. |
