Connectors Guide
Connector overview
Supply Connector
Drive Supply Protection Requirement
On power up, it is essential that the input voltage to the drive is below 4V if executed soon after a power down.
Note that this is a requirement for both single and dual power supply. For dual power supply, both the main and the logic power supply must be below 4V before a new power up is executed. Please note that the time required for the drop to 4V might be different for the main and the logic supply input.
The time required for the voltage to drop below 4V is application specific and can be estimated experimentally with the use of an oscilloscope with the probe placed at the input to the drive.
Battery Powered Applications
Many battery powered applications have a switch or a relay integrated between the battery and the drive. This scenario might cause the voltage to bounce on power on. The voltage can drop to values that can damage the drive (please refer to the minimum input voltage of the drive within the Product Specification manual of your drive).
In such cases, we advise adding a capacitor between the switch/relay and the drive. This will smoothen the voltage input on power on.
The capacitance is application specific and can be estimated experimentally. It is important for the capacitance to be dimensioned in a way that the voltage does not drop below the minimum input voltage of the drive + 0.5V.

Note | ||||
Both network connectors have the same pinout, thanks to auto-negotiation there is no need to make crossed-cables. I.e. TX+ of one device can be connected to TX+ of another. Note that port 0 should be used as EtherCAT IN and port 1 as EtherCAT OUT. The safety signals are bypassed between connectors P3 and P4 to facilitate the daisy chain connection of communications and safety signals. Find more information in the Communications page. |

Common mating terminals and cables for all signal connectors
All signal connectors are of Molex Pico-Clasp™ family. All share the same crimp terminals and jumper wires. Given the small size of the connectors, crimping must be done with appropriate tools and application guides provided by Molex. Otherwise, it is strongly recommended to buy pre-crimped jumper wires and connect to your system using split (or butt) terminals. Spiral wraps are recommended to order and protect the thin wires and make tidy, elegant wiring.
