Check travel
Determining the approach
direction of the motor
Tab. 3 Definitions
1. Start a check travel and limit it to low dynamic response.
In spite of equal control, even motors of the same type turn in the opposite direction due to differ-
ent wiring.
The DNCE has a clockwise-rotating spindle: When the drive shaft is rotated in a clockwise direction,
the piston rod moves in the direction of the motor.
2. Start homing in accordance with the operating instructions for your motor drive system limited to
low dynamics up to the reference switch.
Providing the permitted impact energy is not exceeded, reference travel in conjunction with motor
type MTR-DCI may be made directly against the mechanical end position on the motor side.
Maximum impact energy (= ½ mass x speed
– DNCE-32 :
– DNCE-40 :
– DNCE-63 :
3. Start a test run and limit it to low dynamic response.
4. Check whether the DNCE fulfils the following requirements:
– The piston rod must move through the complete intended positioning cycle.
– The piston rod must stop as soon as it reaches a limit switch.
5. If the proximity sensors do not respond:
