Safety Precautions
NOTICE
Damange due to manual displacement!
Manual displacement can cause irreparable damage to the piezo modules in the
NEXACT® linear motor.
Do not displace the moving platform of the PIFOC® Z-drive with NEXACT®
linear motor manually!
NOTICE
Fixed operation frequency for permanent operation!
For permanent operation of the drives do not exceed operation frequencies of
800 Hz.
NOTICE
Unsuitable cables!
Unsuitable cables can damage the electronics.
Only use cables from PI for connecting the N-725.2A to the electronics.
INFORMATION
Extended cables can affect the performance of the N-725.2A.
Do
not
use cable extensions. If you need longer cables, contact our customer
service department (p. 6).
Installation
Connecting the N-725.2A to a Protective Earth Conductor
NOTICE
Ground loops with double connection of protective earth conductor!
In the case of Z drives with Sub-D connectors, ground loops can occur when the Z
drive is grounded via its protective earth connection as well as by the shield of the
connection cable for the electronics.
If a ground loop occurs, contact our customer service department (p. 6).
The N-725.2A is grounded when it is connected to the piezo controller via its HD sub-D15m
connector. However, to comply with the 2004/108/EC, EMC Directive, a functional grounding is
required for potential equalization.
