KOLLMORGEN 60WKS-CE240/22PB servo amplifier

KOLLMORGEN 60WKS-CE240/22PB servo amplifier

 

The 60WKS series of servo amplifiers in 240 V technology are set up for driving the SM series of synchronous servo motors with RLG/tacho-feedback and trapezoidal commutation. The power section is implemented as a 3-phase, pulse-width modulated transistor stage. The motor speed and the trapezoidal output currents are controlled by PI-controllers. The phase-switching of the motor and tacho windings are controlled by the electronic rotor-position sensor (RLG) of the motor.

 

Amplifier 60WKS-CE240/xx-PB:

– power feed via 3-phase isolating transformer
– PSU, ballast circuit and ballast resistor are integrated.

 

Function groups 60WKS
3-phase power supply unit with smoothing capacitors
Ballast circuit with -w- characteristic
Auxiliary supply, to generate the auxiliary voltages from the DC-link voltage
(alternatively, an external 24V-supply, Option -24V-)
3-phase output stage for 4-Q operation
2 differential inputs for setpoints, setpoint 2 is adjustable
Enable-input
Limit-switch inputs (Option -01-)
PI / current / speed controller
Trimmer potentiometer and fixed components for all the important operating parameters
– on the plug-in custom p.c.b.
Expansion slot for Option p.c.b. -01- with limit-switch logic and ramp generator
Input for 3-phase, brushless or DC-tacho
Input for rotor position sensor (RLG)
Ready/standby relay with isolated contact for fault signalling
24 V logic with isolated optocouplers for control signals, PLC-compatible
LEDs for all important operating states
±15 V auxiliary voltage outputs

 

When the motor is braked, energy is fed back into the servo amplifier. This energy is dissipated as heat in the ballast resistor. The ballast resistor is switched into action by the ballast circuit. The response of the circuit begins at a DC-link voltage of 285 V, and is indicated by a blinking of the internal yellow LED D83. As the loading is repeated, the built-in -w- characteristic causes the threshold to rise to 300 V, so that there is power-sharing between more than one module, if they are parallel-connected on the same DC-bus.
