ETH Mounting Instructions
14 192-550002N10 ETH March 2019
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 16)
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.
The internal end stops of the electro cylinder may under no circumstances be
accessed during operation. The internal end positions may only be accessed by
the cylinder in setup mode and only for determining the end positions resp. for
relubrication with a low force of a few N (torque limitation if possible below 10 %)
and very slowly (max. 2 % of the nominal speed).
The lifetime of the electro cylinder depends strongly on the degree of power
exploitation and on impermissible operating states occurring - even if only for a
short time.
Depending on the operating conditions (rotation speed, load, etc.) increased
surface temperature in the area of the drive may occur. When touching it during
operation slight injuries from burning may occur. Don't touch the product during
operation. At maintenance, service and repair always take care that the product is
cooled off before starting work.
