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" 

 

 
 

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 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.
