Process control expansion modules for servo motors
21 February 2012
JVL has introduced two process control expansion modules for its MAC400 (400W) and MAC3000 (3,000W) motors, which are aimed at process control applications with 4-20mA analogue control signals. The interface consists of a 4-20 mA (12 bit) input for controlling the motor position and a 4-20 mA (12 bit) feed-back output that indicates actual position. Both signals have full galvanic isolation and there is a galvanically isolated digital error output.
The P4/P5 module enables a second motor to function as a slave with a very high degree of signal integrity. After configuring both master and slave motors, their built-in high-speed communications interface ensures that the slave will always follow the master. Should an error arise in either the slave or the master then further movement is stopped in both motors.
Features at-a-glance:
Standard M12 connectors (MAC00-P4) for industrial use
Standard M12 and Harting connectors (MAC00-P5) for even higher reliability
4-20mA analogue input. Resolution 16 bit (65.535 step). Galvanically isolated
4-20mA analogue output. Resolution 16 bit (65.535 step). Galvanically isolated
Error output, digital. Galvanically isolated
Communication interface for slave motor (including +24V control voltage for slave motor)
Optically isolated communication via RS232 or RS485
Full RS232 protocol support using standard serial cables
RS232 communication interface for PC setup and monitoring
Input for 24Vdc control voltage which could also be used for a possible slave motor
