Wiring Control Circuit Terminals; Wire Sizes - YASKAWA Varispeed E7 Instruction Manual And Parameter Description

Wiring Control Circuit Terminals

Wire Sizes

For remote operation using analog signals, keep the control line length between the Analog Operator or oper-
ation signals and the Inverter to 50 m or less, and separate the lines from main power lines or other control cir-
cuits to reduce induction from peripheral devices.
When setting frequencies from an external frequency source (and not from a Digital Operator), used shielded
twisted-pair wires and ground the shield for the largest area of contact between shield and ground. See the fig-
ure below for details on the wiring.

* 1. Use shielded twisted-pair cables to input an external frequency reference.
* 2. Refer to Table 2.3 Lug Sizes
* 3. We recommend using straight solderless terminal on signal lines to simplify wiring and improve reliability.
