400W Rushed Card Machine PWM Servo Amplifier Torque Control IP20
Designed and produced by market demand, EP3 series Multifunctional
AC Servo Driver adopts advanced control algorithm and intelligent
power module (IPM), which could realize precise digital control on
torque speed and position.
Designed on the basis of EP2 series, functions of USB Interfaces ,
sustaining Modbus agreement and internal simple PLC are added. This
series includes 3-phrase 220V series and 3-phrase 380V series. The
feedback mode is 2500 line incremental encoder or 17 bit absolute
encoder, which could support 16 bit current sampling and 16 bit
external analogue sampling accuracy.
1. Position Control Mode:super-speed optoisolated plus/signal ,CCW/CW,signal and A/B phase
Signal control mode. It adopts Pulse receiving mode of Differential
drive, which could inhibit disturbing effectively. Optional command
pulse filters smoothly so that the system could operate stably
during accelerating and decelerating. It adds digital filtering and
detection mode of pulse signal.
2. Simulation Command Control:speed and torque use the same analog input,difference or single
terminal analog signal -10V～10V. Analog input has normal bias which
could be compensated by parameters. In speed control mode,it offers
internal speed with No 1~8 selected by input terminal. The internal
speed could be adjusted. Optional parameters set, speed command and
acceleration and deceleration time make the system operate stably
during accelerating and decelerating. In torque control mode,it
offers internal torque with No 1~4 selected by input terminal. The
internal torque could be adjusted.
3. Resonance Inhibition:could be realized by adjusting internal parameters and notch
4. Newest digital control technology including dedicated DSP and
super-scale CPLD specialized for motor control.
5. Supports absolute type and incremental type MSL / MAL Series
6. Supports full-closed loop control.
