1.12 Conditions of utilization
General introductory notes
With the electro cylinder you bought a product which was manufactured and tested
before delivery with the utmost care.
Please take your time to read the following notes which you ought to follow closely
during setup and operation.
The operation of the electro cylinder is only permitted within the limit values stated
in this manual.
Unless, all claims under the warranty will become void and a reduced service life or
even damages must be expected.
Please compare the operating data with the stated limit values especially
with reference to:
Stroke length and setting of the limit switches, those must be set so that there is a
sufficient safety travel at both ends of the travel stroke
Even if the limit switches were already mounted at our premises, they must be
adapted according to suitable values before operation!
Thrust and traction force in the effective direction
Lateral force (e.g. as a component of the effective force, but also due to own
weight on horizontal mounting, especially with parallel motor mounting and long
travel strokes)
Speed
Acceleration
Environmental conditions (e.g. temperature, contamination)
Please do take possible pulses caused by moved masses into consideration for
the operating data. (Even small abrupt loads can cause damage, especially if
they occur rather often at the same place.)
The limit values for the thrust and traction force, lateral force, speed and
acceleration are partly influenced by several factors and can change
depending on:
The size of the electro cylinder
Screw lead
Direct or parallel drive via toothed belt transmission
Mounting method
Mounting orientation vertical or horizontal resp. inclined
Travel Stroke
Note on cylinder mounting
Do always use all available mounting possibilities and respect the requirements
listed in chapter "Screw tightening torques for the mounting of the ETH cylinder
by the customer". (see page 25)
If the motor used with the electro cylinder should be able to exceed individual limit
values of the cylinder, the respective values for the motor must be limited in the
control by appropriate parameterization. The parameterization should even be
reduced down to the values necessary for operation.
This would, for example provide a hint to a possible damage or to preventive
maintenance if wear-induced extensive friction of the machine or cylinder would
trigger an error message of the controller.
