DCS-5020 is a microcontroller based PWM drive for permanent magnet DC (PMDC) motors with supply voltage up to 240 VDC and maximum current up to 50 A.
The output stage of the drive is realized with high power IGBT transistors and is galvanically separated from the logical (control) part of the drive.
Drive is based on a 16-bit microcontroller with implemented PID control algorithm. As the feedback of DC motor position an incremental encoder with phase-shifted square signal is used. Encoder interface enables 1x, 2x and 4x incremental encoder resolution.
The driver has a built-in dynamic brake circuit that is activated in case the DC motor is operating in generator mode and if the supply voltage exceeds 255 VDC. An external braking resistor is needed.
Adjustment of all DC servo drive DCS-5020 parameters is performed by using the free configuration software ServoTune3. ServoTune3 software has implemented PID auto tune algorithm.
The input control interface enables control via opto-isolated lines in following modes:
- STEP/DIR/ENABLE,
- CW/CCW/ENABLE,
- Encoder follower in 1x, 2x and 4x decoding,
as well as via analog input within the range 0–5 V with and without feedback (there is the connector on the drive for connecting an external potentiometer).
The build-in soft start enables DC motor 1s after powering on decreasing electric shock on start.
There is an opto-isolated output on drive named Track Error which is activated if adjusted value of tracking error offset is exceeded. That output can be used for activation of external circuit for DC motor emergency stop.
Drive has over-voltage and over-temperature protection.
