S700 Safety Guide | 2 English
Automatic Restart!
The drive might restart automatically after power on, voltage dip or interruption of the supply
voltage, depending on the parameter setting. Risk of death or serious injury for humans work-
ing in the machine. If the parameter AENA is set to 1, then place a warning sign to the
machine (Warning: Automatic Restart at Power On) and ensure, that power on is not pos-
sible, while humans are in a dangerous zone of the machine. In case of using an undervoltage
protection device, you must observe EN 60204-1:2006 chapter 7.5.
Hot surface!
The surfaces of the servo amplifiers can be hot in operation. Risk of minor burns!
The surface temperature can exceed 80°C. Measure the temperature, and wait until the motor
has cooled down below 40°C before touching it.
Earthing!
It is vital that you ensure that the servo amplifier is safely earthed to the PE (protective earth)
busbar in the switch cabinet. Risk of electric shock. Without low-resistance earthing no per-
sonal protection can be guaranteed.
High voltages!
The equipment produces high electric voltages up to 900V. During operation, servo amplifiers
may have uncovered live sections, according to their level of enclosure protection. Capacitors
can have dangerous voltages present up to 10 minutes after switching off the supply power.
There is a risk of death or severe injury from touching exposed contacts. Do not open or touch
the equipment during operation. Keep all covers and cabinet doors closed during operation.
Touching the equipment is allowed during installation and commissioning for properly qualified
persons only.
There is a danger of electrical arcing when disconnecting connectors, because capacitors can
still have dangerous voltages present after switching off the supply power. Risk of burns and
blinding. Wait at least 10 minutes after disconnecting the servo amplifiers from the main sup-
ply power before touching potentially live sections of the equipment (such as contacts) or
removing any connections. Always measure the voltage in the DC bus link and wait until the
voltage is below 60 V before handling components.
Reinforced Insulation!
Thermal sensors, motor holding brakes and feedback systems built into the connected motor
must have reinforced insulation (according to IEC61800-5-1) against system components
with power voltage, according to the required application test voltage. All Kollmorgen com-
ponents meet these requirements.
Never modify the servo amplifiers!
It is not allowed to modify the servo amplifiers without permission by the manufacturer. Open-
ing the housing causes loss of warranty and all certificates become unvalid.
Warning signs are added to the device housing. If these signs are damaged, they must be
replaced immediately.
