Description
The Yaskawa CACR-SR07BE12M is a high-performance digital servo amplifier engineered for precise industrial motion control. It receives command inputs from a master controller or PLC to regulate the position, velocity, and torque output of matched industrial servo motors in automated machinery.

Engineering Context and Field Integration
When commissioning or replacing the CACR-SR07BE12M in a motion control axis, integration technicians and field engineers should adhere to the following setup guidelines:
- EMC and Grounding Compliance: Route motor power cables and encoder feedback lines separately from general I/O wiring. Terminate the motor cable shield 360 degrees to the cabinet ground plane using EMC-compliant metal clamps to suppress high-frequency PWM noise emissions.
- Parameter Backup: Always upload and save the drive’s parameter configuration file using Yaskawa engineering software prior to swapping units. Restoring parameters to a replacement drive ensures correct electronic gear ratios, loop gains, and torque limits match the mechanical axis.
- Thermal Clearance: Maintain minimum vertical and horizontal spacing inside the control panel. Forced-air cooling relies on unobstructed airflow across the internal heatsink fins to prevent thermal trip events during high-duty-cycle operation.
Frequently Asked Questions
What causes an overvoltage (Al.100) alarm on this drive?
An overvoltage fault typically occurs when regenerative energy from a rapidly decelerating high-inertia load cannot be dissipated quickly enough. Verify that the internal or external braking resistor is wired correctly and that its parameters match the actual deceleration profile.
Can this drive be tuned automatically without manual gain calculation?
Yes. The drive supports software-based tuning functions (such as one-touch tuning and autotuning) via the serial communication port, which automatically calculate optimal speed and position loop gains based on the connected load inertia.
What should I check if the servo refuses to turn on (Servo ON signal ignored)?
Verify that all hardware safety interlocks, such as the emergency stop circuit and base block / safe torque off (STO) inputs, are closed and supplied with the correct voltage level. Check the drive’s front digital operator or software diagnostic window for active interlock status flags.
