7.1 Important Notes
High EMC Voltage Level!
Risk of electrical shock, if the servo amplifier (or the motor) is not properly EMC-grounded.
Do not use painted (i.e. non-conductive) mounting plates.
In unfavourable circumstances, use copper mesh tape between the earthing bolts and
earth potential to deflect currents.
Protect the drive from impermissible stresses. In particular, do not let any components
become bent or any insulation distances altered during transport and handling. Avoid con-
tact with electronic components and contacts.
The drive will switch itself off in case of overheating. Ensure that there is an adequate flow
of cool, filtered air into the bottom of the control cabinet, or use a heat exchanger (
Do not mount devices that produce magnetic fields directly beside the drive. Strong mag-
netic fields can directly affect internal components. Install devices which produce magnetic
field with distance to the drives and/or shield the magnetic fields.
7.2 Guide to Mechanical Installation
The following tools are required (at a minimum) to install the AKD2G; your specific install-
ation may require additional tools:
M5 hexagon socket-cap screws (ISO 4762)
4 mm hexagon ball head screwdriver
No. 2 Phillips head screwdriver
Small slotted screwdriver
Install the drive unit as follows:
1. Prepare the site.
Mount the drive in a closed control cabinet (ambient conditions (
# 31)). The site must
be free from conductive or corrosive materials. For the mounting position in the cabinet
(
2. Check ventilation.
Check that the ventilation of the drive is unimpeded, and keep within the permitted ambi-
ent temperature (
# 31). Keep the required space clearance above and below the drive
3. Check the cooling system.
If cooling systems are used for the control cabinet, position the cooling system so that
condensation water cannot drip onto the drive or peripheral devices.
4. Mount the drive.
Assemble the drive and power supply near each other on the conductive, grounded
mounting plate in the cabinet.
5. Ground the drive.
For EMC-compliant shielding and grounding, (
# 52). Ground the mounting plate, motor
housing and CNC-GND of the control system.
