Initial Operation
The following describes the initial operation, which makes the start easy.
Connect the whole system according to
Minimum equipment
To control a motor with the D3 dryve, a minimum equipment has to be provided by the user:
1.
Power supply with 24 V up to 48 V and connecting cables
2.
Stepper motor with suitable cable
3.
Switches/signa generator/microcontroller/PLC
WARNING!
•
Fire hazard
Faulty settings of the motor controller can lead to extremely high motor temperatures.
NOTE
A faulty connection can damage or destroy the motor controller.
DANGER!
•
Danger of falling load
Never work under unsecured vertical axes and loads.
Secure the axis or load against falling by a mechanical safety device or other approved safety method.
