3.2.2 Example of I/O Signal Connections in Speed Control (Analog Voltage
Reference)
Connection example in speed control is as shown below.
∗1. represents twisted-pair wires.
∗2. If using an absolute encoder, allocate the SEN signal to one of the seven input signals.
∗3. Enabled by the parameter setting.
∗4. The 24-VDC power supply is not included. Use a 24-VDC power supply with double insulation or reinforced insula-
tion.
∗5. Always use line receivers to receive the output signals.
