2.1.4 Personnel qualification
This description is only intended for trained specialists in control, automation and drive
engineering who are familiar with the applicable national standards.
2.2 Special safety instructions for AX5000
The safety instructions are designed to avert danger and must be followed during
installation, commissioning, production, troubleshooting, maintenance and trial or test
assemblies.
The servo drives of the AX5000 series are not designed for stand-alone operation and must
always be installed in a machine or system. After installation the additional documentation
and safety instructions provided by the machine manufacturer must be read and followed.
WARNING
Serious risk of injury through high electrical voltage!
•
Never open the servo drive when it is live. Wait until the DC link
capacitors are discharged. The voltage measured between the “ZK+ and
ZK-“ and “RB+ and “RB-“ terminals must have fallen below 50 V.
Opening the device (with the exception of expansion card slots)
invalidates all warranty and liability claims against Beckhoff Automation.
• Negligent, improper handling of the servo drive and bypassing of the
safety devices can lead to personal injury or death through electric
shock.
• Ensure that the protective conductor is connected properly.
• Disconnect the servo drive from the mains supply and secure it against
reconnection before connecting or disconnecting the pluggable terminals.
• Disconnect the servo drive from the mains supply and secure it against
reconnection before working on electrical parts with a voltage > 50 V.
• Due to the DC link capacitors dangerous voltage may persist at the DC
link contacts “ZK+ and ZK-“ and “RB+ and RB-“ after the servo drive has
been disconnected from the mains supply. After disconnecting the servo
drive wait at AX5160/AX5172 15 minutes, at AX5190/AX5191 30 minutes
and at AX5192/AX5193 45 minutes and measure the voltage at the DC
link contacts ZK+ and ZK-. The device is safe once the voltage has fallen
below 50 V.
WARNING
Serious risk of injury through hot surfaces!
•
The surface temperature may exceed 50 °C, resulting in a risk of burns.
• Avoid touching the case during or shortly after operation.
• Leave the servo drive to cool down for at least 15 minutes after it is
switched off.
• Use a thermometer to check whether the surface has cooled down
sufficiently.
WARNING
Danger of injury due to uncontrolled movements!
Read and take note of chapter 6 ‘Important information for commissioning’
each time before commissioning the AX5000
