Overview

50W to 5kW,  1/3-phase, 200V 

200W to 5kW, 3-phase, 400V 

Response frequency: 2kHz bandwidth (velocity response)

Fast response allows precise processing of metal surfaces

Figure: Numerous interference bands

Ultrafast response frequency: 3.2kHz bandwidth (velocity response)

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.

Improved vibration suppression

Vibrations when braking to a standstill have now been significantly reduced. This has shortened the transient recovery time considerably.

Manual and automatic notch filters

Highly sensitive notch filters log vibration frequencies and adapt them automatically.

Manual and automatic damping filters

servo_drives_minas_a6sf_manual_automatic_damping_filters.png

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.

Safety functions based on safety standards:

ISO13849-1 (PLe, CAT3), EN61508 (SIL3), EN62061 (SILCL3), EN61800-5-2 (SIL3, STO), IEC61326-3-1, IEC60240-1.

Modbus RTU: Simple complete motion control solution with one Panasonic compact PLC

servo_drives_minas_a6sf_modbus_rtu.png
  • 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)

servo_drives_minas_a6sf_block_operation.png

Up to 256 block can be controlled via I/O terminal units, PLCs, switches, etc.
