A new LLRF control system for the synchrotron at WERC is in under development. The current system consisted of DDS (Direct Digital Synthesizer), DSP (Digital Signal Processor) and analog RF circuits has been working for 20 years with making a continuous improvement in it. However the current system becomes deteriorated and can not be maintained. The new system utilizes modern FPGAs and MicroTCA.4. The new system consists of three AMCs. One is for feedback control of RF frequency and the others are for processing beam position signals. We describe details of the system and the progress of the off-beam commissioning in this report.
