Contactors When selecting contactors, take into consideration the circuit's inrush current and the maximum momentary current. The Servo Driver inrush current is covered in the preceding explanation of nofuse-breaker selection, and the maximum momentary current is approximately twice the rated current. The following table shows the recommended contactors.

Since switching takes place inside the Servo Drivers, harmonic current leaks from the armature of the motor. With inverter leakage breakers, harmonic current is not detected, preventing the breaker from operating due to leakage current. When selecting leakage breakers, remember to also add the leakage current from devices other than the Servomotor, such as machines using a switching power supply, noise filters, inverters, and so on. For details on leakage breakers, refer to the manufacturer's catalog. The following table shows the Servomotor leakage current for each Servo Driver model. Driver R7D-APA3L to -AP04L R7D-APA3H to -AP04H R7D-AP08H 29 mA 14 mA 16 mA Leakage current (direct measurement) (including high-frequency current) Note 1. The above leakage current is for cases where Servomotor power line length is less than 5 meters. (It varies depending on the Servomotor cable length and the insulation. ) Note 2. The above leakage current is for normal temperature and humidity. (It varies depending on the temperature and humidity. ) Leakage Breaker Connection Example AC power supply side Surge absorber Noise filter 1 NF 4 2 5 3E6 Servo Driver side No-fuse breaker Leakage breaker 3-24 System Design and Installation Chapter 3 Harmonic Current Countermeasures (DC Reactor) The DC Reactor is used for suppressing harmonic currents. It suppresses sudden and quick changes in electric currents. In September 1994, the Ministry of International Trade and Industry established guidelines for the suppression of harmonic waves emitted from home and general electric appliances. To comply with the guidelines, appropriate measures are required to suppress the influence of harmonic waves on power supply lines. Select the proper DC Reactor model according to the Servo Driver that is to be used.

If cables are long and are coiled, mutual induction and inductance will increase and will cause malfunctions. · When installing noise filters for Encoder Cables, use clamp filters. The following table shows the recommended clamp filter models. Maker Tokin TDK Name EMI core Clamp filter Model ESD-QR-25-1 ZCAT2032-0930 ZCAT3035-1330 ZCAT2035-0930A · Do not place the Encoder Cable in the same duct as Control Cables for brakes, solenoids, clutches, and valves. 3-25 System Design and Installation Chapter 3 Improving Control I/O Signal Noise Resistance Positioning can be affected and I/O signals can error if control I/O is influenced by noise.
