Cable Length between Drive and Motor The E7 should be installed as close as possible to the motor to minimize the length of load side power cable needed between the Drive and the motor. If the cable between the Drive and the motor is long, the high-frequency leakage current will increase, causing the Drive output current to increase as well.
A2 signal employed is 4 to 20 mA with parameter H3-08 set for “2: 4 - 20 mA”. For 0 to 10 VDC, parameter H3-08 is set for “0: 0 - 10 VDC” and the E7 control board DIP switch S1-2 must be in the OFF position. (See Fig 2.4).
Wiring Checks After all wiring is completed, perform the following checks: Is all wiring correct? Have all wire clippings, screws or other foreign material been removed from the Drive enclosure? Are all terminal screws tight? Electrical Installation 2 - 13...

Sinking/Sourcing Mode The input terminal logic can be switched between sinking mode (0V common) and sourcing mode (+24V common) by using the terminals SN, SC, and SP. An external power supply can also be connected, providing more freedom in signal input methods.
Control Circuit Wiring Precautions Observe the following precautions when wiring control circuits: Separate control wiring from power/motor wiring (terminals R/L1, S/L2, T/L3, U/T1, V/T2, W/T3, 2, and 3) and other high-power lines. Separate wiring for control circuit terminals MA, MB, MC, M1, M2, M3, and M4 (digital outputs) from wiring to other control circuit terminals.
