NOTICE
Considerable wear due to high operating frequency!
A high operating frequency in step mode can cause considerable wear on the
mechanical system.
When the E-870 drive electronics is used:
−
If necessary, reduce the values of the parameters
PIShift Steps per
Second
(ID 0x1F000600) and
PIShift Frequency
(ID 0x1F000400) on the
drive electronics, see documentation of the drive electronics.
When the E-871 controller is used:
−
When the
PIShift Open-Loop Driving Mode
(ID 0x1F000702) parameter
has a value of 0 (step mode) and motions in open-loop operation are initiated
with the SMO command: The step frequency depends directly from the
control value commanded with SMO and is limited by the value of the
Maximum Motor Output
(ID 0x9) parameter. If necessary, reduce the
commanded control value and the value of the
Maximum Motor Output
parameter.
Reduce the operating time with a high operating frequency (p. 50).
Stop the motion immediately if an electronics malfunction occurs.
NOTICE
Operating voltage too high or incorrectly connected!
Operating voltages that are too high or incorrectly connected can cause damage to
the Q-522.
Only operate the Q-522 with controllers/drivers and original accessories from PI.
Do
not
exceed the operating voltage range (p. 49) for which the Q-522 is
specified.
Only operate the Q-522 when the operating voltage is properly connected; see
"Pin Assignment" (p. 57).
NOTICE
Reduced lifetime of the piezo actuator due to permanently high voltage!
The permanent application of a high static voltage to piezo actuators leads to a
considerable reduction in the lifetime of the piezo ceramic of the stage.
When the Q-522 is not used, switch off the electronics.
