Frequently Asked Questions
What kind of motors does this module control?
It sends signals to control servo drives or variable frequency drives (VFDs). It does not power the motor directly.
Can I connect a normal proximity sensor to its input?
Yes. Its 24V digital inputs can connect to sensors, push buttons, or relay contacts.
What is the “flying actual value setting” function?
This lets you update the target position while the axis is still moving. It is useful for conveyor applications.
Is electrical isolation provided for safety?
Yes. The digital inputs and outputs are isolated from the module’s internal logic for protection.
What is a common installation mistake?
Not using shielded cable for encoder wires. This causes noise and false position readings. Always use proper cable.
