General Warnings - THORLABS Z8 Series User Manual

2.2 General Warnings

Warning
To avoid injury never put anything in the gap between the Actuator and any rigid
structure.
Caution
If the actuator encounters a hard stop while still in the middle of its range (i.e. a
translation stage at the end of its travel range), the motor should be stopped as
soon as possible to prevent damage to the gear head or motor and to keep the
unit from overheating.
When the Z8 motors are fitted to certain optomech products e.g. the GNL series
Goniometers, it is possible that the motor will reach the mechanical hardstops
of the stage before the motor limit switches are activated. In this case, DO NOT
continue to drive the motor into the hardstop as this will damage the motor. As
a guide, the total current drawn should not exceed 80 mA.
Caution
The control PC used to operate the driver for the Z8 series actuators must be
running APT Software version 2.8.0 or higher.
Earlier versions of software do not support this product.
Caution
When storing these units, be sure to fully retract the lead screw to protect the
threads from damage. Improper connection of the motor will result in permanent
damage. All power supplied to the motor should be turned off before altering
any connections to the motor. Check all connections before supplying power to
the motor.
