Wiring With Resolver - Toshiba TOSVERT VF-AS3 Option Instruction Manual

2.2.4 Wiring with resolver

When wiring, follow the instructions below.
- Use multi-layer shielded cable
- Use twisted pair for S1/S3, S2/S4 and R1/R2 each
- For R1/R2 pins, parameter set-up according to your resolver is also needed (See 3.1.1)
- Do not connect any wire to unused pins
- Recommended wire size is 0.25 mm
voltage (R1 and R2)
- The cable length is 100 m at maximum.
• Use Multi-layer shielded cable and connect the shield to housing of 15pin D subminiature connector.
Use of unshielded cable or improper shield grounding can result in malfunction or accident.

action
With OFF, free-run stop
Forward rotation with ON and
reduce speed and stop with OFF
Torque control with ON and reduce speed
and stop with OFF.
Set <F114 : Terminal S1 function 1> to "112".
*1 Assign ST (standby) function to arbitrary terminals.

• Separate the interconnection cable between your resolver and this option 20cm or more away from
power (Power supply and motor) cable to prevent from the signal disruption by noise immunity.
• Do not connect/disconnect the cable when the power on. it can damage the option.
• When prohibition on reverse rotation is set by the inverter parameter <F311: Reverse inhibited> = "1"
and when the motor is rotating to reverse direction due to an external force, the inverter starts with
Important
reverse operation in accordance with the motor's rotation direction for a time and the motor will be able
to shift to the forward rotation and the smooth startup becomes possible.
