Safety
2.6 Responsibility
Electronic devices are not fail-safe. The installer and/or operator of a complete machine
or system is responsible:
y For ensuring the drive is rendered safe if the device fails
y For ensuring the safety of personnel and machinery
y For ensuring the complete machine is in correct working order
y For the risk assessment on the complete machine or system according to
EN ISO 12100 (formerly DIN EN 1050) and EN ISO 13849-1
(formerly DIN EN 954-1)
Pay attention to the topic of “Electrical equipment of machines” in EN60204-1:2006
“Safety of machinery”. The safety requirements on electrical machines dened there are
intended to protect personnel and machinery or systems.
The emergency stop function (as per EN 60204) shuts down the supply of power to a
machine, which results in the drives coasting down in an uncontrolled manner. To avert
hazards, check whether it is appropriate:
− To keep individual drives in operation
− To initiate specic safety procedures
− To incorporate a Safe Torque Off function (Safe Torque Off: movement stop
by "switching off the electrical supply" - STO)
2.4.1 The ServoOne multi-axis system
The ServoOne supply unit is intended for use in a ServoOne multi-axis system.
The multi-axis system comprises at least one ServoOne CMP supply unit with the mains
connection set and several ServoOne DC axis controllers connected to it. In motor
operation the supply unit draws energy from the supply system and makes it available to
the DC axis controllers connected via the DC link. In regenerative operation the energy
is stored in the DC link. Temporarily surplus energy is fed back to the supply system in
sinusoidal form by the supply unit.
2.4.2 Repair
Only have repairs undertaken by authorised repair shops. Unauthorised opening and
incorrect intervention could lead to death, injury or damage. The warranty provided by
KEBA will be rendered void.
