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 mm2 (AWG23) for signal line (S1,S2,S3,S4), 0.5 mm2 (AWG20) for excitation
voltage (R1 and R2)
- The cable length is 100 m at maximum.

CAUTION
Mandatory
action
• 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.
Important
• 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
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.
Torque control with ON and reduce speed
and stop with OFF.
Set <F114 : Terminal S1 function 1> to “112”.

3.1 Performance of vector control with resolver
Using the sinusoidal wave feedback signal from the resolver installed on the motor shaft or load rotation shaft, vector
control with sensor can be conducted.
Speed control operation: 0 speed to 150% torque,
speed control range: 1:1000
speed accuracy: ±0.02% (50Hz base digital input)
Torque control operation: Torque control accuracy: ±10%
(torque control range: -100% to 100%)
3.1.1 Parameter setting for vector control with resolver
During operation with vector control with sensor, it would be necessary to set the following parameters shown
below.
■ Set V/f pattern
Table 3-1. parameter of control pattern
When conducting vector control with sensor (speed/torque control) with this board option, <Pt> = “10”, “11”, “12” should
be set.
For torque control operation, it is necessary to allocate control switching (torque/position) to one of the terminal function
selection <F111> to <F118> (input terminal function selection 1 to 8) (when <CMOd> =“0”) or to allocate to
communication control switching (when <CMOd> =“2” to “5”), in addition to the above parameters.
For details of adjustment methods by the speed control command and torque control command, refer to the Function
manual for torque control (E6582106).

3.1.2 Monitoring method for feedback amount
Motor rotation speed can be monitored.
The motor is equipped with status monitor which is displayed on the panel and analog monitor which used analog
output terminals ([FM], [AM] terminals)
Set items (1) or (2) for motor speed monitoring.
(1) Speed feedback (real-time value) with sign(+/-) (Unit: Hz/free unit)
The real-time display of motor speed can be made (Monitor display setting: “153”).
(2) Speed feedback (one-second filter) with sign(+/-) (Unit: Hz/free unit)
The filtered motor speed (feedback value) is displayed. (Monitor display setting: “154”).
The monitoring for the above (1) or (2) is possible also in cases except for <Pt> = “10, 11, 12 (PG feedback vector
control operation)”. For example, the monitoring can be used for confirmation of the initial PG feedback amount in
open loop (V/f operation and the like).
<Setting method for status monitoring>
In order to monitor motor rotation speed in condition monitoring, it is necessary to change the setting for extended
parameters (<F710> to <F718>).
Refer to Monitoring Operating Condition section of the inverter manual.
<Setting method for analog monitoring>
In order to monitor motor rotation speed by the analog output terminal, it is necessary to change the setting for basic
parameters (<FMSL>, <FM>).
Refer to Meter Setting and Calibration section of the inverter manual.
3.1.3 Confirmation of resolver's rotational direction
Resolver’s connection in Sin, Cos waves and rotational direction of motor can be confirmed as follows.
Set the parameters changed back to the original values following confirming the rotational direction.
(1) Set parameter <Pt: V/f pattern> = “0: constant torque characteristics”.
(2) Set parameter <F711: status monitor 1 display selected> = “153: Signed speed feedback (real-time value)”.
(3) Enter an operating command for positive rotation and command frequency of 1-10Hz to the inverter.
(4) Confirm the motor be turning in the positive direction.
(5) Display status monitor “1” by using the status monitor indication of inverter.
(6) Monitor display, when resolver signal input is determined positive turn 3Hz, “+3.0” is indicated into the display.
When it is determined negative turn 3.0Hz, “-3.0” is indicated. When determined negative rotation, resolver's
Sin, Cos waves connections and motor wiring are not correct. They must be corrected.
3.1.4 Abnormal speed detection function
■ Parameter

Title Function Name Adjustment Range Default Setting
F622 Abnormal speed detection time 0.01 – 100.00sec 0.01
F623 Abnormal speed increase band 0.0: Disabled, 0.01 – 30.00Hz 0.00
F624 Abnormal speed decrease band 0.0: Disabled, 0.01 – 30.00Hz 0.00

E6582171
■ Functions
If speed feedback (Estimated speed) > (Output frequency + <F623>) or speed feedback (Estimated speed) < (Output
frequency - <F624>), and a certain period of time set with <F622: Abnormal speed detection time>, a trip occurs.
You can provide range for a detection level of a trip with a setting of <F623: Abnormal speed increase band> and <F624:
Abnormal speed decrease band>.
During torque control, if speed feedback (Estimated speed) > (Speed upper limit + <F623>) or > (Speed lower limit
- <F624>) a certain period of time set with <F622: Abnormal speed detection time>, “E-13” trip occurs.
3.1.5 Accuracy of speed control
The accuracy of speed control with the PG feedback can be obtained by the following formulae.
Accuracy of speed control = Command frequency accuracy + feedback detection accuracy
Command frequency accuracy =
(using digital command)
Feedback detection accuracy =
FC: Inverter output frequency
P : Number of motor poles
PG : 2048
PH : 4
RT: Speed response, see the value in the table below as a reference
3.1.6 Easy positioning PID control
■ Functions
This function, which is aimed at a retaining the load at standstill at its normal stop position, is used along with the speed
sensor vector control function to prevent the position of an elevator at standstill from shifting.
Switching to position control takes place when the load is at a standstill.
The settings of these parameters take effect only in sensor speed control mode.
