The motors are connected according to
fig. 9-12 "NY4125 motor connection
circuit (3 half bridges, HB0_1/2/3)" on page 98
The half bridges HB1_0/1/2, HB2_0/1/2, HB3_0/1/2, and HB4_0/1/2 are
identical to HB0_0/1/2.

Notes
1. Follow this cabling instruction:
Shielded cable is recommended, but not mandatory.
If shielded cable is used, the shielding on the NYCe 4000 side of the
cable must be connected to Shield (house connector).
Connect the other side to a convenient metal part or leave it open.
2. Connect the DR_GND of the drive power to the housing and/or safety
earth (if this is not already the case).
3. Connect the NYCe 4000, a power supply or other equipment on a metal
frame or mounting base and make sure there is a galvanic contact.
4. A fuse must be installed between the +V of the drive power supply and
DP_PWR on the node. The fuse is mandatory by safety regulations and
must be UL recognized. See NYCe 4000 Standard Housings and
Accessories manual for detailed information about fuses.
5. Connect an external capacitor close to the drive module (see
16.1 "Drive Power Filtering for NY412x/NY4140" on page 213
), in
order to avoid ripple currents.
