It rotates in the following direction.
Note: Synchronous operation in the direction opposite to the reference PG rotation
If the slave motor
receives a run reverse
command (REV):
To drive the slave PG in the direction opposite to the reference PG rotation in synchronous
operation, connect the B and A phase output signals issued from the reference PG to terminals XA
and XB, respectively. (See Table 1.3.)

1.3.3 Wiring procedure for the PGs and the synchronous operation card
• Turn the inverter's power OFF and wait for at least five minutes before starting
connection.
• Qualified electricians should carry out wiring.
Otherwise, electric shock could occur.
• Noise may be emitted from the inverter, motor and wires. Implement appropriate
measure to prevent the nearby sensors and devices from malfunctioning due to such
noise.
Otherwise, an accident could occur.
Wire each PG to the synchronous operation card, observing the following precautions and referring
to the connection diagrams given in Figures 2.1 and 2.2.
(1) Turn the inverter's power OFF.
(2) Use a shielded wire for wiring between the PG and the synchronous operation card.
(3) To prevent malfunction due to noise, keep the wiring away from the main circuit wiring of the
inverter and the power wiring of other devices as far as possible (at least 10 cm). Do not route
them in the same duct.
(4) Complete the wiring for the PG before turning the inverter's power ON.
(5) The wire size applicable to the option connection terminal on the inverter is AWG 18-24.
When using a wire with its end being stripped, strip its end by 5 to 7 mm. When using a ferrule,
use a vinyl-insulated ferrule.
Loosen the fixing screw, insert the wire end into the opening of the terminal block, and tighten
the screw.

Chapter 3 PREPARATION FOR OPERATING
After completion of mounting and wiring but before turning the inverter's power ON, check the
followings.
(1) The wiring is correct.
(2) There is no cable waste or screws left.
(3) The screws and terminals are firmly tightened.
(4) The straggling wires at ferrules are not short-circuited to other terminals.
Furthermore, after powering the inverter ON but before starting inverter operation, check the
followings.
• Check the wiring surely before running the inverter. Incorrect wiring causes the inverter
or other devices to malfunction.
Failure to do so could cause failure or injuries.
• Be sure to mount the terminal cover before turning the power ON.
Do not remove any cover while the power is ON.
Doing so could cause electric shock.
• Confirm and adjust the configuration of the function codes before running the inverter.
Otherwise, an accident could occur.

Chapter 4 SYNCHRONOUS OPERATION CONTROL
The synchronous operation control enables the slave inverter to detect the reference motor rotation
with PG signals and synchronize the slave motor with the reference motor in rotation speed and
position.
The synchronous operation is available in three modes--Speed synchronous (o60 = 0), standby
synchronous (o60 = 1), and simultaneous start synchronous (o60 = 2) operation.
Reference motor's PG signals should be input to terminals XA, XB, and XZ, and slave motor's ones,
to terminals YA, YB, and YZ.

4.2 Overview of Synchronous Operation
4.2.1 Standby synchronous operation
In standby synchronous operation (o60 = 1), the inverter controls the slave motor to synchronize its
Z phase with the reference motor's Z phase, based on the first detected Z phases (positions) of those
two motors after the start of synchronous operation. The slave motor could cause a single cycle
delay at a maximum (on standby) at the start of operation.
Once the slave motor starts running after standby, it will never go standby unless the synchronous
operation is cancelled (see Note 1 below).
The Z phase synchronization angles of the reference and slave motors can be adjusted with the
function code o66.
The inverter integrates the position pulses for each of the reference and slave motors and controls
the slave motor's rotation speed and position to keep the difference between those two motors
(hereafter called deviation) at zero.
If any incorrect count due to electrical noise or other factors is found in the integrated count of A/B
phases, the inverter corrects the error based on the Z phase difference.
If the deviation between those two motors falls below the synchronization completion detection angle
(specified by o67), the SY synchronization completion signal will be issued. If synchronization is lost
so that the deviation exceeds 100 times the excessive deviation setting (specified by o68), the
inverter shuts down its output with the Ero alarm.

Note 1: Synchronous operation cancellation conditions
The synchronous operation is canceled when:

Page 17
4.2.2 Simultaneous start synchronous operation
In simultaneous start synchronous operation (o60 = 2), the inverter controls the rotation speed and
position of the slave motor to maintain the phase difference between the reference and slave motors
at the time when the single motor drive operation is switched to the synchronous operation. That is,
it keeps the deviation between the integrated position pulses of the reference and slave motors at
zero.
If the deviation falls below the synchronization completion detection angle (specified by o67), the SY
synchronization completion signal will be issued. If synchronization is lost so that the deviation
exceeds 100 times the excessive deviation setting (specified by o68), the inverter shuts down its
output with the Ero alarm.
If any incorrect count due to electrical noise or other factors is found in the integrated count of A/B
phases, the inverter corrects the error based on the Z phase difference.
If the run command for the slave motor is turned OFF, the inverter continues to monitor the motor
positions as long as the synchronous operation is not switched to the single motor drive operation.
When the run command is turned ON again, the inverter restarts to control the slave motor to
maintain the Z phase difference between the reference and slave motors.

4.6 Configuring Function Codes
To enable synchronous operation, be sure to select the speed control with optional PG interface
(F42/A14 = 3, 4). Other function codes should be configured as described below.
When configuring the function codes, refer to Chapter 5 "FUNCTION CODE CONFIGURATION
EXAMPLES AND ADJUSTMENT GUIDE."
4.6.1 Motor constant data
Configure function codes F03 to F05, P01 to P03, P06 to P12 and P99, referring to the FRENIC-Multi
Instruction Manual (INR-SI47-1094-E), Chapter 5 "Function Codes."
When using motor 2, configure A01 to A03, A15 to A17, A20 to A26, and A39.
4.6.2 Data setting for synchronous operation
F01 Frequency Command 1
C30 Frequency Command 2
Select the pulse train input (F01/C30 = 12) as a reference command source.
Switching between synchronous operation and single motor operation is possible using the
Hz2/Hz1 terminal command (see Figure 4.4). The switching example is given below.
(Example) Turning terminal [X1] ON for single motor operation during which a digital
frequency command drives the inverter
Set F01 and C30 data to "12" and "0," respectively. And set E01 data to "11" to assign the
Hz2/Hz1 command to terminal [X1].
It is recommended to perform switching between synchronous operation and single motor
operation when the inverter is stopped. Switching when the inverter is running may activate
the protective function. To avoid it, decrease the difference between the output frequency and
the reference frequency after switching.

F07 Acceleration Time 1
F08 Deceleration Time 1
E10 Acceleration Time 2
E11 Deceleration Time 2
Also in synchronous operation, the inverter controls the output frequency according to the
acceleration/deceleration time as usual. Specify the acceleration/deceleration time as short
as possible. Be careful that, if the acceleration/deceleration time longer than that of the
reference inverter is specified, the following capability of the slave motor will be lost.
F42 Control Mode Selection 1
A14 Control Mode Selection 2
For synchronous operation, set the F42 (A14) data to "3" or "4" to select the V/f control with
optional PG interface or dynamic torque vector control with optional PG interface,
respectively.
o01 Reference/Slave PG Input (Input mode)
For synchronous operation, the o01 data is fixed to "2: A/B phase pulse."
o02 Speed Control (P Gain)
o03 Speed Control (Integral time)
These function codes specify the PI constants of the slave motor's speed controller. The
expression below shows the transfer function of the regulator.

o04 Speed Control (Filter time constant)
This function code specifies a time constant determining a linear delay of the low pass filter for
the speed command given by pulse train. Use this function code to suppress an overshoot
that occurs, for example, when the speed command varies.
o05 Reference PG Pulse (Encoder pulse resolution)
o09 Slave PG Pulse (Encoder pulse resolution)
Set the encoder pulse resolution of the reference motor to o05, and that of the slave motor
(driven by the inverter) to o09. For position synchronization (o60 = 1 or 2), be sure to use PGs
with the same encoder pulse resolution for both the reference and slave motors. When o05 =
0, the inverter recognizes that o05 = o09 and operates accordingly.
o06 Reference PG Pulse (Filter time constant)
o10 Slave PG Pulse (Filter time constant)
o06 and o10 specify time constants determining a linear delay of the low pass filter for the
speed feedbacks given by reference and slave PGs, respectively. Use these function codes,
for example, when the large ripple components superpose the feedback pulse train.

For synchronous operation, it is recommended that the reduction ratios (pulse count factors)
of the reference and slave sides be identical. To make them identical, set both o07 and o08
data to "0," applying the pulse count of the slave PG to that of the reference PG. If the
reduction ratios are different between the two, refer to Section 5.1 "Typical Configuration and
Pulse Setting."

o13 Speed Control (Output limiter)
This function code specifies the output limit percentage for the speed controller (PI controller).
Specification of 100.00% is equivalent to the maximum speed (maximum frequency).
To suppress the frequency control amount (PI controller output) to the extent of the motor's
slip frequency in the speed control mode, use this function.
o60 Synchronous Operation (Mode selection)
This function code specifies the synchronous operation mode.

o61 Synchronous Operation (Main speed controller gain)
This function code is fixed at 1.0 and cannot be changed.
o62 Synchronous Operation (APR P gain)
This function code determines the response of the automatic position regulator (APR). (See
Figure 4.4.)
If the APR output reaches the maximum frequency when the phase angle deviation (position
deviation) between the reference and slave PGs becomes equal to the pulse rate at the
maximum frequency, that gain is assumed to be 1.0.
Setting a too large value to the gain data easily causes hunting, and setting a too small value
results in a large steady-state deviation.
o63 Synchronous Operation (APR positive output limiter)
o64 Synchronous Operation (APR negative output limiter)
These function codes specify the limits of APR output relative to the reference motor speed.
(See Figures 4.4 and 4.6.)
Specification of "999" disables the limiter.

If the APR output reaches the maximum frequency when the phase angle deviation between
the reference and slave PGs (position deviation) becomes 10% of the pulse rate at the
maximum frequency, that gain is assumed to be 1.0.
o66 Synchronous Operation (Synchronous offset angle)
In standby synchronous operation, the slave inverter delays starting to synchronize the Z
phase of the slave motor with that of the reference motor by the offset angle specified by this
function code.
o67 Synchronous Operation (Synchronization completion detection angle)
This function code specifies the synchronization completion detection angle.
If the absolute value of the phase angle deviation (position deviation) between the reference
and slave PGs becomes equal to or below the synchronization completion detection angle
specified by o67, the inverter issues a synchronization completion signal SY, provided that
the E20, E21, or E27 data (Terminal function) is set to "29" (Synchronization completed).
Once turned ON, the synchronization completion signal SY is kept ON for 100 ms.

5.4 Checking PG Pulse Rate
Before starting synchronous operation, run the motors separately and check that the data settings
for number of motor poles (P01), encoder pulse resolution (o09), and pulse count factor 1/2
(o11/o12) conform to the actual system configuration.
The PG pulse rate can be checked with the keypad by using Menu #4 "I/O Checking, item 4_15: PG
pulse rate 1 (reference side)" and "item 4_17: PG pulse rate 2 (slave side)." For details, refer to the
FRENIC-Multi Instruction Manual (INR-SI47-1094-E), Section 3.4.5 "Checking I/O signal status."
Given below is an example of checking PG pulse rate.
(Example)
No. of motor poles = 4P (P01 = 4)
Encoder pulse resolution = 1000 P/R (o09 = 1000)
Pulse count factor 1/2 = 1/30 (o11 = 1, o12 = 30)
Under these above conditions, run the motor at 20 Hz. Then the motor speed and the pulse rate
can be calculated as follows.
Motor speed (r/min) = 120 x Frequency/No. of poles = 120 x 20/4 = 600 (r/min) = 10 (r/s)
Pulse rate (p/s) = Motor speed (r/s) x Encoder pulse resolution (P/R) x Pulse count factor 1/2
= 10 x 1000 x 1/30 = 333.3333 ≈ 333 (p/s)
Use Menu #4 "I/O Checking, item 4_17" and check that "0.333" is displayed on the keypad. Note
that, on the keypad, displayed value = pulse rate (p/s)/1000.
Note: The maximum input pulse rate that the synchronous operation card (OPC-E1-SY) supports
is 30 kp/s. If the pulse rate from the PGs exceeds the maximum limit, synchronous operation is not
available.

Chapter 6 PROTECTIVE FUNCTIONS
If any inverter protective function is activated to issue an alarm, the inverter displays the
corresponding alarm code on the LED monitor of the keypad and shuts down its output. Accordingly,
the motor coasts to a stop.
Table 6.1 lists alarm codes related to the synchronous operation card. For other alarm codes, refer to
the FRENIC-Multi Instruction Manual (INR-SI47-1094-E), Chapter 6 "TROUBLESHOOTING."

Y: Always active. The protective function for the alarm is always active when the control is enabled.
C: Conditionally active. The protective function for the alarm is active when the control is enabled and
the protective function is enabled with the function code. The factory default is "enabled."
NA: Not available when the control is enabled.

If any of the protective functions has been activated, first remove the cause. Then, after checking
that the all run commands are set to off, reset the alarm. Note that if the alarm is reset when any
run command is set to on, the inverter may supply the power to the motor, which may cause the
motor to rotate.
Injury may occur.
6.1 Overspeed Alarm (OS)

Alarm code Descriptions
• The inverter issues this alarm when the detected speed exceeds the 1.2 times
the minimum value of either (1) or (2) below.
(1) For the selected motor,
OS
Maximum frequency (F03 or A01) + Torque limiter (Frequency increment
limit for braking, H76)
(2) Frequency limiter, High (F15)
• This protective function works when the inverter is outputting with the speed
control with PG being enabled (F42 or A14 = 3 or 4 and PG/Hz is ON).

6.2 Excessive Speed Deviation Alarm (ErE)

Alarm code
ErE
• This protective function recognizes a PG error by software based on the
relationship between the speed command and the detected speed.
• When the speed deviation between the speed command and the detected
speed has exceeded the excessive speed deviation level specified by o17
during the period longer than the timer setting specified by o18, the protective
function issues this alarm.
• This protective function provides two choices--"Stop running" (o19 = 1 or 2)
and "Continue to run" (o19 = 0) when it is activated. When the latter is
selected, the inverter continues to run with output to terminal [Y] without
issuing an alarm.
• This protective function works when the inverter is outputting with the speed
control with PG being enabled (F42 or A14 = 3 or 4 and PG/Hz is ON). It does
not, however, during DC braking or idling due to overload.
• This alarm occurs when no Z phase is detected although the slave PG has
rotated two cycles or more in synchronous operation.
This alarm is contained in alarm category "Y" in Table 6.1, so it cannot be
disabled by any function code.
