2.1. Pre-Installation Instructions

(1) Make sure that the input power of the inverter is off and make sure the charge light is off. (2) When the FR-A5AP unit is used for PLG feedback control or orientation control, a PLG (motor with PLG) and
external power supply are required.
When PLG feedback control and orientation control are used together, the PLG (motor with PLG) and external power
supply are shared between these controls.
(3) When the FR-A5AP unit is fitted, the programmed operation function is made invalid.
CAUTION
With input power on, do not install or remove the option unit. Otherwise, the inverter and option unit
may be damaged.

2.2. Installation Procedure

(1) Securely insert the connector of the option unit far into the connector of the inverter. At this time, also fit the option
fixing holes securely.
(2) Securely fix the option unit to the inverter on both sides with the accessory mounting screws. If the screw holes
do not match, the connector may not have been connected correctly. Check for loose connections.
CAUTION
When installing the inverter front cover, the cables to the inverter's control circuit terminals and option terminals should be routed properly in the wiring space to prevent them from being caught between the inverter and its cover.

Note:1. When the motor with a PLG used is other than the standard motor with PLG (SF-JR), the pin numbers
are different. To reduce radiated noise, connect the shield wires of the PLG cables to the CG.
2. When orientation control is used with PLG feedback control, the PLG and 5V power supply may be shared between these controls.
3. Couple the PLG in line with the motor with a speed ratio of 1 to 1 without any mechanical looseness.
4. Keep the accessory jumpers connected. However, when the same PLG is shared between the FR-A5AP and another unit (e.g. NC) which is connected with a terminal resistor, the built-in terminal resistors are
not required and should be removed. (Terminal resistors: 100)
5. Assign this function to any of the input terminals using Pr. 180 to Pr. 186 "input terminal function selection".
6. Assign this function to any of the output terminals using Pr. 190 to Pr. 195 "output terminal function selection".
7.When the stop position command is entered from outside the inverter (externally), the FR-A5AX inboard option is required.

Used to input digital signals through either relays or open collector transistors. As the command signals are ent ered, speed or position commands are selected using Pr. 360. Used when a digital signal read timing signal is necessary. Data is only read while terminals DY-SD are shorted. By opening terminals DY-SD, the data before opening is retained. Common terminal for digital signal input terminals and data read timing signals When connecting the transistor output (open collector output) of a programmable controller (PC), etc., connect the external power common (positive) to this terminal to prevent a fault occurring due to leakage current
When terminals DY-SD are open, the inverter does not import data. Therefore, if the input status of the X0-X11 signals change, the stop position data before opening of terminals DY-SD is valid. Also, the position data is imported on the leading edge of the DY signal.
Note: Pr. 300 to Pr. 304 settings for the FR-A5AX are made invalid when the stop position is set to be specified
from outside the inverter (externally), with the FR-A5AP (orientation control option) fitted to the inverter and when orientation control is used. Pr. 300 to Pr. 305 of the FR-A5AX are made valid when the stop position is not set from outside the inverter.

(8) Pr. 364 "PLG stop check time".
When the in-position signal has not yet been output in orientation operation, the orientation fault signal is output if orientation cannot be completed and the PLG is stopped for the period of time set in Pr. 364. When the in­position signal has been output once, the orientation fault signal is output if the orientation cannot be completed again within the time set in Pr. 364.
(9) Pr. 365 "orientation time limit".
If orientation cannot be completed within the time set in Pr. 365, which is measured from when the current position signal has passed the creep select position, the orientation fault signal is output.
(10) Pr. 366 "recheck time".
If the start signal is switched off with the orientation command ON after the PLG is stopped under orientation control, the current position is checked again after the time set in Pr. 366 has elapsed and the in-position signal or orientation fault signal is output according to the check result.
24

3.7. Operation

(1) Orientation starting during rotation.
1) The orientation command (X22) causes the motor to decelerate to the orientation speed set in Pr. 351.
2) After the orientation speed is reached, the motor decelerates to the creep speed set in Pr. 352 as soon as the current position signal reaches the creep select position set in Pr. 353.
3) Furthermore, the position loop begins to work as soon as the current position signal reaches the position loop select position set in Pr. 354.
4) After the position loop is selected, the motor keeps decelerating until the current position signal reaches the DC dynamic braking start position set in Pr. 355, at which time DC dynamic braking is started to stop the motor.
5) When the motor has stopped within the in-position zone set in Pr. 357, the in-position signal (ORA) is output with a delay of the in-position signal output delay time set in Pr. 363. If the current position signal comes out of the in-position zone due to external force etc., the in-position signal is switched off with a delay of the in­position signal output delay time set in Pr. 363.
6) The orientation fault signal (ORM) is output if the orientation cannot be completed within the time set in Pr. 365 after the current position signal has passed the creep select position.
7) If the orientation (once started) has been stopped by an external force etc. before the in-position zone is reached and the in-position signal (ORA) is not yet output, the orientation fault signal (ORM) is output after the PLG stop check time set in Pr. 364 has elapsed. If the current position signal comes out of the in-position zone due to an external force etc. after the output of the in-position signal (ORA), the in-position signal (ORA) is switched off after a delay of the in-position signal output delay time set in Pr. 363. If the orientation cannot be completed within the PLG stop check time set in
Pr. 364, the orientation fault signal (ORM) is output.
8) When the start signal (STF or STR) is switched off with the orientation command on after the in-position signal (ORA) or orientation fault signal (ORM) has been output once, the in-position signal (ORA) or orientation fault signal (ORM) is output again after the recheck time set in Pr. 366 has elapsed.
25
9) The in-position signal (ORA) and orientation fault signal (ORM) are not output if the orientation command is off.

Note: If the orientation command is switched off with the start signal remaining on, the motor accelerates toward
the command speed.
29
1) Selection of servo torque function until the in-position signal is output. Set Pr. 358 "servo torque selection" to determine whether servo torque is required or not. When the current position signal is between the orientation stop position and DC dynamic braking start position, servo torque is not generated. The shaft is held by DC dynamic braking. If the current position signal comes out of this zone due to external force, etc., servo torque is generated to return the current position signal to within the zone. Once the in-position signal is output, operation is performed in accordance with the setting in 4).
2) Retry function. Set Pr. 358 "servo torque selection" to determine whether the retry function is required or not. Note that this function cannot be used with the servo torque function. If the motor shaft is confirmed to have stopped but is not in the in-position zone, the retry function causes the shaft to be oriented again. This retry is made three times, including the first orientation, but no more than three times. (The orientation fault signal is not output during retry operation.)
3) Frequency compensation function for use when the motor shaft has stopped outside the in-position zone. When the motor shaft has been stopped by external force, etc. before entering the in-position zone, the output frequency is increased to move the shaft to the orientation stop position. This output frequency rises gradually to the creep speed set in Pr. 352. This function cannot be used with the retry function.
4) Selection of whether DC dynamic braking or servo torque is started when the motor shaft comes out of the in­position zone after the in-position signal has been output once. You can select whether to start DC dynamic braking to lock the shaft or to start servo torque to return the shaft to the orientation stop position if the motor shaft comes out of the in-position zone due to external force, etc. after the output of the in-position signal.
5) Selection of DC dynamic braking, servo torque or orientation termination timing. To terminate orientation, switch off the start signal (STF or STR) and then switch off the orientation command (X22). At this time, you can select the point of switching off the in-position signal between when the start signal is switched off or when the orientation command is switched off.
6) In-position signal OFF selection; for use when the motor shaft comes out of the in-position zone after the in­position signal is output once. You can select either the mode in which the in-position signal is switched off when the motor shaft comes out of thein-position zone or the mode in which the in-position signal remains on (orientation fault signal is not output) when the motor shaft comes out of the in-position zone.
30
(5) Pr. 362 "position loop gain"
When Pr. 358 "servo torque selection" value has been set to choose the servo torque function, the output frequency provided to generate servo torque rises gradually up to the creep speed set in Pr. 352 according to the inclination set in Pr. 362 "position loop gain". Increasing the setting will increase the operation speed but may cause the machine to hunt.
(6) Monitoring functions
Monitoring Description
Position signal monitoring Set "19" in Pr. 52 to display the position signal on the PU
instead of the voltage (Displayed only when the FR-A5AP is fitted.) Set "22" in Pr. 52 to display the orientation status on the PU instead of the output voltage. (Displayed only when the FR­A5AP is fitted.) 0 - Orientation not selected (i.e. orientation mode has not been activated) or orientation speed has not been reached. 1 - Orientation speed reached.
Orientation status
2 - Creep speed reached. 3 - Position loop reached. 4 - In-position. 5 - Orientation fault (pulse stop). 6 - Orientation fault (orientation time limit elapsed). 7 - Orientation fault (recheck). 8 - Positioning orientation in progress.
Servo torque will return the motor to the stop position (if enough torque can be provided) if it is moved from the stop position. Servo torque is available in all modes vector, V/f, etc. When orientation control is selected.
31

3.8. Instructions

(1) T he PLG should be coupled with the motor shaft or the spindle oriented with a speed ratio of 1 to 1 without any
mechanical looseness.
(2) The DC dynamic brake operated for positioning must be released in the shortest time (within several seconds).
Operating the brake continuously can cause the motor to generate heat and burn out.
(3) The servo lock function is not available after positioning stop. If the spindle must be held securely, prepare an
appropriate holding means such as a mechanical brake or a dowel pin.
(4) To ensure correct positioning, the PLG must be set in the proper rotation direction and the A and B phases
connected correctly.
(5) The orientation fault signal may be output if the pulse signal is not given from the PLG during orientation due to
an open cable, etc.
(6) When orientation control is exercised, orientation cannot be completed if "no DC dynamic brake operation" is set
in the DC dynamic brake adjusting (voltage, frequency, time) parameters. These parameters must be set to operate the DC dynamic brake.
(7) To terminate orientation, the start signal (STF or STR) must be first switched off and the orientation signal (X22)
must be switched off. As soon as this orientation signal is switched off, orientation control ends. (Depending on the setting of Pr. 358 "servo torque selection", when the orientation signal remains on, orientation will continue even if the DC dynamic brake is released as soon as the start signal is switched off. Hence, the orientation status monitored is not set to 0.)
(8) When the retry function has been selected in Pr. 358 "servo torque selection", retry is made three times.
(Note: The first orientation counts as 1 retry.)
(9) For orientation control, set correct values in Pr. 350 "stop position command selection" and Pr. 360 "12-bit data
selection". If the values set are incorrect, proper orientation control will not be performed.
(10)The value set in Pr. 11 (DC dynamic brake operation time) should be any of 1 to 10. If "8888" (DC dynamic brake
external selection) is set in Pr. 11, the DC dynamic brake is not operated unless the X13 terminal signal is switched on. For orientation control the DC dynamic brake is operated independently of the X12 signal.
(11)When orientation control is exercised, PID control is invalid.

4. PLG FEEDBACK CONTROL

This function is used with a speed detector (PLG) to allow the motor speed to be detected by the speed detector and fed back to the inverter so that the output frequency of the inverter is controlled to keep the motor speed constant to load variations. Pr. 367 "speed feedback range" is factory-set to "9999" and Pr. 370 "control mode selection" to "0", making this function invalid.

3. Couple the PLG in line with the motor with a speed ratio of 1 to 1 without any mechanical looseness.
4. Keep the accessory jumpers connected. However, when the same PLG is shared between the FR-A5AP and the other unit (e.g. NC) which is connected with a terminal resistor, the built-in terminal resistors are

The either of the following motors may be used. Set the number of motor poles according to the motor used:
Standard motor (with PLG) : SF-JR 0.2kW to 55kW
Constant-torque motor (with PLG): SF-JRCA 0.4kW to 55kW
Note:1. For vector control, this parameter value is made invalid and the setting of Pr. 81 "number of motor poles"
is made valid.
2. If you set this parameter value to "0, 10 or 110" and operate the inverter, any of E.OP1 to E.OP3 occurs.
3. If you set "102, 104, 106 or 108", that value minus 100 is set as the number of poles.

Make sure that Pr. 80 "motor capacity", Pr. 81 "number of motor poles", Pr. 144 "number of motor poles", Pr. 369 "number of PLG pulses", Pr. 359 "PLG rotation direction" and Pr. 370 "control mode" values are set properly. (Refer to Section 4.6 "Pre-Operation Settings and 4.7 "Control Mode Setting".)
(1) Pr. 367 "speed feedback range".
This parameter is used to make the PLG feedback function valid. Set the speed feedback control range. (When Pr. 367 = 9999 (factory setting), the PLG feedback function is invalid.)
<Setting>
Define the upper and lower limits in reference to the set value (frequency at which the motor is to be rotated at constant speed). Normally, set the frequency converted from the rated motor speed (rated load) and slip (r/min). Too large setting will result in slow response.
Example: Rated speed of a 4-pole motor is 1740r/min (60Hz) Slip Nsp = synchronous speed - rated speed
= 1800 - 1740 = 60 (r/min)
Frequency equivalent to slip (fsp)

(2) Pr. 368 "feedback gain".
This parameter is valid when PLG feedback control is valid. Set if rotation is instable or response is slow. When the setting is greater than 1, response is faster but overcurrent or rotational instability is more liable to occur. When the setting is less than 1, response is slower but rotation is more stable.
(3) Instructions for PLG feedback control.
1) The number of motor poles used must be checked before starting operation. The number of poles set must be correct to ensure proper control of the motor.
2) The PLG should be coupled in line with the motor shaft without any mechanical looseness with a speed ratio of 1 to 1.
3) Make sure that the PLG has been set to the correct rotation direction on the rotation direction display of the parameter unit. If the rotation direction is not correct, PLG feedback control cannot be carried out (the inverter can be operated).
4) During acceleration or deceleration, PLG feedback control is not performed to prevent instability such as hunting. PLG feedback control is started after the output frequency has once reached the [set speed]  [speed
feedback range].
5) If any of the following conditions occurs during PLG feedback control operation, the inverter is run at the output frequency of [set speed]  [speed feedback range] without coming to an alarm stop and does not follow up the
motor speed:
The pulse signal from the PLG is switched off due to an open cable, etc.
An accurate pulse signal cannot be detected due to induction noise, etc.
The motor is forced to accelerate (regenerative operation) or decelerate (e.g. motor lock) by large external
force.
6) When opening the brake of the motor with brake, use the RUN (running) signal. (The brake may not be opened if the FU (output frequency detection) signal is used.)
7) During PLG feedback control, do not switch off the 5V power of the PLG. If the power is switched off, normal PLG feedback control cannot be exercised.
8) Programmed operation cannot be performed in the PLG feedback control mode (when the FR-A5AP is fitted).

9) Set Pr. 285 "overspeed detection frequency" to prevent misoperation caused if an accurate signal cannot be detected from the PLG. This shuts off the output and gives an inverter alarm (E.MB1) when;
(detection frequency) - (output frequency) > Pr.
285.

4.9. Vector control

Vector control can be performed using the standard motor with PLG. Make sure that Pr. 80 "motor capacity", Pr. 81 "number of motor poles", Pr. 144 "number of motor poles", Pr. 369 "number of PLG pulses", Pr. 359 "PLG rotation direction" and Pr. 370 "control mode" values are set properly. (Refer to Section 4.6 "Pre-Operation Settings and 4.7 "Control Mode Setting".) Servo lock will resist and attempts to move it from the stop position, the limitation is the amount of torque that can be provided. Servo lock is only available in vector control mode (when using a PLG).
(1) Zero speed control and servo lock
<Zero speed control> When the Pr. 370 value is "1" and Pr. 80 and Pr. 81 values are not "9999", zero speed control is made valid so that torque may be generated at zero speed. Use Pr. 22 to set the torque limit level in the zero speed control mode. (150% torque (short duration) is possible.)
<Servo lock> When the Pr. 370 value is "2" and Pr. 80 and Pr. 81 values are not "9999", servo lock is made valid. Use Pr. 22 to set the torque limit level in the servo lock mode. (150% torque (short duration) is possible.) Also, use Pr. 375 "servo lock gain" to set the servo lock gain. A high setting will make response faster but increase the probability of instability.
When GD
2
(inertia) is large, a high servo lock gain setting will increase the probability of instability.

Torque limit may be activated only when vector control is selected. The second and third functions are Pr. 48 "second torque limit level" and Pr. 144 "third torque limit level". When vector control is not selected, the stall prevention functions are activated. Use the same parameter numbers for setting. The Pr. 22 setting may be changed during operation. When Pr. 22 = "9999", the torque limit level may be set by entering a signal into the No. 1 terminal. At this time, the auxiliary input override function of the No. 1 terminal is not activated.

2.Continuous, repetitive operation of 50%ED can be performed in cycle time of 10 minutes. Note that the maximum continuous operation time is 5 minutes.
3.Use the constant-torque motor (SF-JRCA with PLG) when 50%ED with 100% torque is required for 2.2kW or more at 900r/min or less.
4.Use the constant-torque motor (SF-JRCA with PLG) when continuous 100% torque is required for 2. 2kW or more at 600r/min or less.
5.To provide 150% torque from 0Hz to the rated speed of the motor the inverter should be one rank higher than t he motor.
6.Cyclic operation when the inverter and motor have the same capacity is possible but typically only 50% torque can be produced.
7.Continuous operation when the inverter capacity is one rank higher than the motor will produce the same results as
when the inverter and motor capacity are the same (as shown above).

(4) Pr. 372 "speed control P gain".
Used to set the proportional gain of the speed loop. A high setting will make the speed response faster but if the setting is too high this will cause vibrations and noise.
(5) Pr. 373 "speed control I gain".
Used to set the integral gain of the speed loop. A high setting will shorten restoration time at occurrence of speed variation but if the setting is too high this will cause speed overshooting.
(6) Driving/regenerative status signal output.
When vector control is selected, the driving/regenerative status is output as a signal. Assign the function of the output signal to any of the output terminals using Pr. 190 to Pr. 195 "output terminal function selection".
(7) Instructions for vector control.
1) When using vector control, perform offline auto tuning in the motor rotation mode (whilst the motor is running).
2) Before starting operation, always confirm that the correct number of poles of the motor used. Proper speed control cannot be performed if the number of motor poles is incorrect.
3) Couple the PLG in line with the motor shaft with a speed ratio of 1 to 1 without any mechanical looseness.
4) Make sure that the PLG has been set to the correct rotation direction on the rotation direction display of the parameter unit. If the rotation direction is not correct, vector control cannot be carried out.
5) In the vector control mode, vector control is also exercised during acceleration/deceleration.
6) When opening the brake of a motor with brake, use the RY2 (operation ready 2) signal. (The brake may not be opened if the FU (output frequency detection) signal is used.)
7) In the vector control mode, the maximum speed is 3600r/min (120Hz). If the speed is increased above that value, it is clamped (limited to 120Hz (3600r/min) ).
8) Do not switch off the 5V power of the PLG during vector control. Proper vector control cannot be performed if that power is switched off.
9) Proper vector control cannot be performed if the pulse signal from the PLG is lost due to an open cable, etc.
49

(Note 1)
Note:1. When the capacity of the inverter is the same as that of the motor, do not set "6" or a higher value in Pr.
72 "PWM frequency selection". When the capacity of the inverter is one rank higher than that of the motor, "6" (appoximately 6KHz) or a higher value may be set in Pr. 72 "PWM frequency selection".
2. In the vector control mode, set the Pr. 72 "PWM frequency selection" value during a stop.

4.10. Additional Functions

(1) Pr. 162 "selection of automatic restart after instantaneous power failure selection".
By setting "2" in Pr. 162, automatic restart after instantaneous power failure can be made at the frequency detected from the PLG. In the vector control mode, automatic restart is made with the PLG detection frequency searched for, independently of the Pr. 162 setting.
Pr. 162 Setting Description
0 (factory setting) With frequency search
1 Without frequency search 2 PLG detection frequency search
(2) Pr. 285 "overspeed detection frequency".
If (detection frequency)  (output frequency) > (Pr. 285 setting), E.MB1 occurs and the output is shut off. When Pr. 285 = 9999, overspeed detection is not performed.

(3) Pr. 374 "overspeed detection level".

(
)
Used to limit the maximum speed. (0 to 400Hz) Any speed higher than the speed set in Pr. 374 is judged as overspeed and the corresponding signal is output. If overspeed is detected, the inverter will not come to an alarm stop.

(5) S-shaped acceleration/deceleration C

When the FR-A5AP is fitted, S-shaped acceleration/deceleration C can be selected by setting "4" in Pr. 29 "acceleration/deceleration pattern". The S-shaped acceleration/deceleration C function allows the speeds of S­shaped acceleration/deceleration to be set in the corresponding parameters and the required parameter to be selected by the S-shaped acceleration/deceleration C switching terminal (X20). Assign the function of the S-shaped acceleration/deceleration C switching terminal (X20) to any of the terminals using Pr. 180 to Pr. 186 "input terminal function selection".

Note: During acceleration/deceleration, switching cannot be made using the S-shaped acceleration/deceleration C switching terminal (X20). When X20 is switched either ON or OFF during either acceleration or deceleration, the effect of the switch (to select a different acceleration or deceleration shape) does not take effect until either the acceleration or deceleration has stopped (i.e. a stable speed has been reached).
