Features and functions

WARNING

Grievous bodily harm due to dangerous move-

ments from falling or dropping axes!

Secure vertical axes against dropping or sinking

after switching off by e.g.:

−

Mechanical locking of the vertical axis

−

External brake, arrestor, clamping device.

−

Weight compensation of the axes

The holding brake itself is not suitable for per-

sonal protection. Ensure protection of individuals

by superordinate protective measures such as

cordoning off of danger zones using protective

fences or grids.

For European countries, additionally comply with

the following standards and guidelines, e.g.

•

EN ISO 13849-1:2015 "Safety of machi-

nery - Safety-related parts of control sys-

tems - Part 1: General principles for

design (ISO 13849-1:2015)" and EN ISO

13849-2:2012 "Safety of machinery. Safety-

related parts of control systems. General

principles for design"

•

Information sheet no. 005 "Gravity-loaded

axes (vertical axes)" published by: DGUV

Fachbereich Holz und Metall (German

Employer's Liability Insurance Association

Wood and Metal)

Determine the safety requirements valid for

the case of application and observe the safety

requirements during plant design. Comply with

national regulations at the installation site of the

system.

Commissioning and maintenance instruc-

tions

That is why the function and the holding brakes

have to be checked in regular intervals and mal-

functions must be removed in an appropriate

period.

Bosch Rexroth AG

The braking effect can be reduced by:

•

Corrosion on friction surfaces, vapor and

sediment

•

Over voltages and too high temperatures

•

Wear (increasing the air gap between arma-

ture and pole)

The holding brake functionality can be checked

mechanically by hand (torque wrench) or auto-

matically by means of the software function.

Manually check holding torque (M4)

Disconnect the motor from the power

supply and secure it against being

switched on again.

Measure the transferable holding torque

(M4) of the holding brake with a torque

wrench.

Check holding torque (M4) automatically

Start the P-0-0541, C2100 Command

Holding system check in drive controller.

The efficiency of the holding brake and the

opened state are checked by starting the

routine.

�� If the holding torque (M4) is not

achieved, the resurfacing routine can

be used to reconstitute the holding

torque. Contact the Rexroth service

department.
