MINAS A6SF servo driver
- 50W to 5kW, 1/3-phase, 200V
- 200W to 5kW, 3-phase, 400V
Response frequency of MINAS A5: 2kHz bandwidth (velocity response)
Fast response allows precise processing of metal surfaces
Figure: Numerous interference bands
Ultrafast response frequency of MINAS A6: 3.2kHz bandwidth (velocity response)
Smooth surface, like a mirror!
Figure: Hardly any interference bands
Real-time auto-gain tuning
Automatic tuning after completion of multiple operations.
The automatic vibration suppression function minimizes damage to the equipment. Additional mode and stiffness parameters enable easy response frequency-optimization for specific machine types such as high-friction, belt-driven machines or machines with low-friction ball screw drives.
Figure: Drive types
- Ball screw drive
- Belt drive
Improved vibration suppression
Vibrations when braking to a standstill have now been significantly reduced. This has shortened the transient recovery time considerably.
Figure: Comparison of transient recovery curves
- Ball screw drive
- Belt drive
Manual and automatic notch filters
Highly sensitive notch filters log vibration frequencies and adapt them automatically.
Manual and automatic damping filters
Damping filters that can be set automatically suppress the equipment's resonance and the natural vibration frequency component of the command input, which greatly reduces axis vibration at machine stoppage.
Improved suppression of load variations
- Reduction of transient recovery time during positioning
- Stable movement for multiple-joint robot With / without load or with variable load
Semi/fully enclosed position control loop
The A6 series enables a setting value of 8Mpps and a response with 4Mpps. This allows for high resolution as well as high-speed operation.
A5: Setting value 4Mpps
A6: Setting value 8Mpps

Modbus RTU: Simple complete motion control solution with one Panasonic compact PLC
- Modbus RTU is an open, serial (RS232 or RS485) protocol based on a master/slave or client/server architecture.
- Widely used protocol due to its ease of operation and reliability.
- Cost-effective solution for programmable controllers based on RS485.
- Servo drives can be controlled based on a CANopen CiA drive profile
Block operation with digital I/Os (like MINAS A4P)
Up to 256 block can be controlled via I/O terminal units, PLCs, switches, etc.
