- 1. For wiring for reference inputs and encoders, use the specified cables. Refer to 4 Specifications and Dimensional Drawings of Cables and Peripheral Devices for details. Use cables that are as short as possible.
- 2. For a ground wire, use as thick a cable as possible (2.0 mm2 (0.079 in2) or thicker).
- 3. Do not bend or apply tension to cables.
- 4. Use a noise filter to prevent noise interference. (For details, refer to 5.6.2 Wiring for Noise Control.)
- 5. To prevent malfunction due to noise, take the following actions:
- 6. Use a molded-case circuit braker (QF) or fuse to protect the power supply line from high voltage.
- 7. The SERVOPACKs do not have built-in ground protection circuits. To configure a safer system, install an earth leakage braker ...
- 5.6.2 Wiring for Noise Control
- (1) Wiring Example
- (2) Correct Grounding
- (3) Using Noise Filters
- 1. Do not put the input and output lines in the same duct or bundle them together.
- 2. Separate the noise filter ground wire from the output lines. Do not accommodate the noise filter ground wire, output lines and other signal lines in the same duct or bundle them together.
- 3. Connect the noise filter ground wire directly to the ground plate. Do not connect the noise filter ground wire to other ground wires.
- 4. When grounding a noise filter inside a unit: If a noise filter is located inside a unit, connect the noise filter ground wire and the ground wires from other devices inside the unit to the ground plate for the unit first, then ground these wires.

- 4. Gradually increase only the position loop gain. When it has been increased about as far as possible, then decrease the Speed Feedback Compensation in Pn111 from 100% to 90%. Then repeat steps 2 and 3.
- 5. Decrease the speed feedback compensation to a value lower than 90%. Then repeat steps 2 through 4 to shorten the settling time. If the speed feedback compensation is too low, however, the response waveform will oscillate.
- 6. Find the parameter settings that yield the shortest settling time without causing vibration or instability in the position error or torque reference waveform being observed with the analog monitor.
