Note 1. Do not use resistances less than than the minimum connection resistance value. Doing so
may damage the Inverter.
Note 2. The usage rate is shown as a percentage of the braking time in one cycle. If one cycle is 10
seconds, for example, one second of braking is possible using a Braking Resistor Unit (10%
usage rate ED). If the usage rate is to be exceeded, a detailed regeneration energy calcula-
tion will be required.

2-2-4 Wiring Control Circuit Terminals
A control signal line must be 50 m maximum and separated from power lines.
The frequency reference must be input into the Inverter through shielded, twisted-pair
wires.
H
Wiring Control I/O Terminals
Wire each control I/O terminal under the following conditions.
