TOX^® ElectricDrive servo press

• Compact design

• Long service life

• Cost-effective

A typical application example is pressing.

• High power density and stiffness

• Very long service life

• Very small design

Typical application examples are punching, press applications with high joining speeds or press applications in limited installation space.

The motor holding brake prevents the weight-loaded working piston from dropping when the system is de-energised.

• Holding load weights on the working piston at standstill: yes

• Automatic closing in the event of a power failure: yes

• Continuous status monitoring: yes

• Suitable for realising machine safety: yes

• Suitable for active braking: no

• Automated cyclical checking of the braking force: no

• Gearbox breakage and toothed belt tear-proof: no

• Recommended for realising personal safety: no

In the event of a malfunction, the safety brake stops the drive and protects against injury. The brake is checked for functionality before each cycle.

• Holding load weights on the working piston at standstill: yes

• Automatic closing in the event of a power failure: yes

• Continuous status monitoring: yes

• Suitable for realising machine safety: yes

• Suitable for active braking: yes

• Automated cyclical checking of the braking force: yes

• Gearbox breakage and toothed belt tear-proof: yes

• Recommended for realising personal safety*: yes

The patented safety brake from TOX^® in combination with a SIL 3 safety encoder mounted directly on the work spindle sets new standards in terms of safety!

• Immediate and unadulterated path and speed detection directly on the work spindle (SIL 3, PLe)

• Continuous, redundant speed monitoring

• Suitable for the realisation of functional safety (e.g. SLS) with performance level e*

• Enables the highest possible level of personal safety**

• Automated cyclical checking of brake functionality

• Continuous mutual monitoring of safety encoder and servomotor resolver*.

* In combination with a suitable evaluation unit (e.g. the TOX^® PowerModule Core with Extended Safety or safety PLC of the system)

**The use of a safety brake with safety encoder as the sole means of ensuring personal safety is not permitted. It is the responsibility of the system manufacturer to create an overall safety concept and carry out a risk assessment as part of the CE approval process. We will be happy to advise you!

We offer so-called type-tested performance level kits for the TOX^® ElectricPowerDrive with safety brake in order to achieve a performance level e (PLe) in the overall system. This is a ready-to-use, assembled and wired module in which only the 400 VAC and 24 VDC power supply and the customer's safety circuit need to be wired. The performance level kit is used to safely control the safety brake in accordance with performance level (PLe). The performance level kit is certified in accordance with Annex IX of the Machinery Directive 2006/42/EC (type examination).
The Ple kit itself consists of the mounting plate, terminals for the power supply, a safety PLC, a brake switching module and the TOX^® PowerModule Core. The kit contains the entire control system - all completely pre-assembled on a mounting plate.

Advantages:

• No additional effort on the part of the customer

• Maximum safety, performance level e

• Autonomous module - immediately ready for operation.
