ctrlX SAFETY "SafeMotion"
Replacing drive components
WARNING
Electric shock due to live parts with more than 50 V!
Replacement may only be performed by personnel
trained and qualified to work on or with electrical equip-
ment.
The brake has to be replaced by a brake of an identical type. Only if the brake
is replaced by a brake of an identical type, is it ensured that all parameter
settings may remain unchanged. Moreover, it is not required to repeat the
acceptance test within the scope of the integrated safety technology.
1. Protect the axis against dropping
DANGER
Dangerous movements! Danger to life, risk of injury,
serious injury or property damage! While the brake is replaced, secure the
axis by a blocking device or by moving the axis to a safe end position.
2. Open the main switch
3. Make sure the main switch cannot be switched back on
4. Disconnect the plug-in connectors
When replacing the brake, cover the open mating sites of power lines
with protective caps if sprinkling with cooling liquid/lubricant or pollution
may occur (admissible pollution degree according to EN50178: 2).
5. Replace the brake
To mechanically replace the brake, observe the instructions of the
machine manufacturer.
6. Reconnect the plug-in connectors
7. Log the replacement in the safety-related documentation of the machine
(serial number, type, …).
11.2.3
Replacing the optional encoder
When replacing optional encoders, comply with the safety instructions in the
chapter “Safety instructions for electric drives and controls”!
WARNING
Electric shock due to live parts with more than 50 V!
Replacement may only be performed by personnel
trained and qualified to work on or with electrical equip-
ment.
The encoder may only be replaced by an encoder of an identical type. Only if
the encoder is replaced by an encoder of an identical type, is it ensured that all
parameter settings remain unchanged. Moreover, it is not required to repeat the
acceptance test within the scope of the integrated safety technology.
1. If necessary, note down the last absolute value
2. Open the main switch
3. Make sure the main switch cannot be switched back on
4. Disconnect the plug-in connectors
5. Replace the encoder
To mechanically replace the optional encoder, observe the mounting
instructions of the encoder manufacturer.
If the optional encoder is used as safety technology encoder, it has to be
ensured that the replacement encoder complies with the requirements of
safety technology! (see ⮫ Required motors and measuring systems).
