The MDS-CH series is Mitsubishi Electric's Combined Hybrid drive platform — a compact drive architecture where multiple servo axis channels are integrated into a single drive unit sharing a common power supply bus. The "CH" designation indicates the combined hybrid design: separate servo amplifier PCBs for each axis channel within one physical drive enclosure.
The MDS-CH-V2-3535 provides two independent servo axis channels — each rated at 3.5kW — in a single unit. The "V2" designates this as the second-generation servo amplifier within the MDS-CH series.

The MDS-CH series integrates within Mitsubishi's drive system architecture:
Power Supply Module (MDS-CH-CV): Converts AC mains to the shared DC bus that supplies all MDS-CH servo and spindle drives in the system.
Servo Drives (MDS-CH-V): Inverter units that control servo motors from the shared DC bus. The MDS-CH-V2-3535 is a dual-channel servo drive in this family.
Spindle Drives (MDS-CH-SP): Inverter units that control spindle motors. The MDS-CH-SP-300 (described below) is the spindle drive in the same system family.
The MDS-CH-V2-3535 connects to the Mitsubishi CNC via the SSCNET (Servo System Controller NETwork) — FANUC's high-speed serial network for servo communication between the CNC and drive amplifiers.
CNC machining centre dual axis replacement: A Mitsubishi CNC machining centre develops servo faults on two axes served by the MDS-CH-V2-3535. Replacement restores dual axis servo control for both affected axes.
CNC drive system commissioning: A new Mitsubishi CNC machine tool is installed. The MDS-CH-V2-3535 is commissioned as the dual servo drive serving two of the machine's axis channels.
Q1: How do I identify which axes are served by the MDS-CH-V2-3535 in my CNC system?
The axis assignment for each MDS-CH drive is determined by the drive's position on the SSCNET communication chain and the axis address settings configured in the Mitsubishi CNC parameters. Check the CNC's drive assignment parameter table or the machine tool's electrical documentation to identify which physical axes correspond to the two channels on MDS-CH-V2-3535.
Q2: Can both channels of the MDS-CH-V2-3535 operate simultaneously?
Yes. Both servo axis channels operate simultaneously and independently — each running its own velocity and current control loops at the servo update rate. The shared DC bus supplies both channels at the same time, enabling coordinated multi-axis motion as commanded by the CNC interpolation.
Q3: What happens if one axis channel fails — does the other channel continue operating?
This depends on the fault type. If the fault is channel-specific (e.g., a motor overcurrent on one axis), the other channel may continue operating while the faulted channel is in alarm. If the fault affects the shared power bus or the SSCNET communication, both channels are affected simultaneously. The CNC's alarm display identifies the faulted channel and fault type.
Q4: Does replacing MDS-CH-V2-3535 require servo parameter backup?
Servo parameters for both axis channels reside in the Mitsubishi CNC's parameter memory — not in the drive unit. Replacing the drive unit does not affect stored CNC parameters. After fitting the replacement, the CNC downloads the relevant axis parameters to the new drive unit during the power-on initialisation sequence.
