How to Wiring
Wire the signals from the external scale to the external scale connector, X5.
1) Cable for the external scale to be the twisted pair with bundle shielding and to hav-
ing the twisted core wire with diameter of 0.18mm
2
.
2) Cable length to be max. 20m. Double wiring for 5V power supply is recommended
when the wiring length is long to reduce the voltage drop effect.

nector X5 of the driver without fail.
4) Separate the wiring to X7 from the power line (L1, L2, L3, B1, B2, B3, U, V. W,
)
as much as possible (30cm or more). Do not pass these wires in the same duct, nor
bundle together.
5) Do not connect anything to the vacant pins of X5.
6) The maximum power available from the connector X5 is 250 mA at 5 V ±5%. If you
use an external scale requiring more power, you should provide the suitable power
source by yourself. Some external scales need longer initialization period after

7) When driving the external scale from an external power supply, keep the EX5V
pin open circuit so that it does not receive any external voltage. Connect the
GND circuit (0 V) to EX0V (connector X5, pin 2) of the driver to eliminate potential
difference.
