CHAPTER 4 - Start-up and adjustment of the drive
4.3.4 Serial interface connector J3
4.3.5 Resolver connector J4
The resolver cable must be of the type approved of by ABB (code 16080125). Connections to
the plug must comply with drawing DMGCAV067, available on request.
As regards the connection of the motor thermal probe, the standard configuration foresees
the short circuit between terminal J4/7 and J4/8, since flag F9, Thermal Probe is set as PTC.
The motor thermal protection is carried out through I
and P19, TH_MOT). The same type of motor thermal protection can be used by configuring
F9 as NTC and leaving terminals J4/7 and J4/8 disconnected.
On request, it is possible to foresee a direct connection between terminals J4/7 and J4/8 and
the thermal probe mounted on the motor (normally closed). Flag F9 is set as PTC. To make
the connection it is possible to use the double wire available in the a.m. cable. This solution is
not advisable to comply with EMC standards.
