Performance Standard
Position Sync
Within ±5 degree, the deviation in position between
the master and the slave during steady-state
operating under the rated load.
Speed Sync
Within a bigger value between ±0.5% and ±5rpm, the
deviation in speed between the master’s order speed
and the slave’s current speed during steady-state
operating under the rated load. (Note2)
Table 3 Performance Standard
(Note2) For example, if the speed of the master’s command is 1800rpm, the
maximum deviation between the speed of the master’s command and the one of the
slave’s command shall be within ±9rpm (=±0.5%). In addition, if the master’s
command speed is 500rpm, the maximum deviation between the speed of the
master’s command and the one of the slave’s command shall be within ±5rpm since
±2.5rpm (=±0.5%) is smaller than ±5rpm.

3. Installation
Step 1
Remove the cover and mount an encoder option card (slot 3) and a
synchronization option card (slot 2) as seen in the figure below. But,
if any inverter is used as the master for the synchronization
operation, the master inverter does not need any synchronization
option card to be mounted (Refer to Step 2).
Step 2
Wire the encoder option card (slot 3)and the synchronization option
card (slot 2) as seen in the figure below. The following figure shows
a wiring example of the case where the master motor’s encoder is
of 5V line driver type and the slave motor’s encoder is of 15V open
collector type.

4. Ready for Synchronization Operation
It is the way how to set the master inverter (DRV-09 Control Mode:
sensored vector operating mode) and the slave inverter (DRV-09
Control Mode: sensored vector operating mode) and tune the
motor before operating the speed (or position) synchronization.
Step 1. Check the motor’s rotating direction
a. Set DRV-01 Cmd Frequency to a low speed (10Hz or below) and set
DRV-06 Cmd Source to Keypad.
b. Set DRV-09 Control Mode to V/F and make a forward command with
keypad and check if plus (+) value is read when monitoring APO-08 Enc
Monitor.
c. If it is minus (-) value, change the setting of APO-05 Enc Pulse Sel to –(A
+ B).
Step 2. Set the encoder option
a. Set APO-01 Enc Opt Mode to Feedback.
b. Input APO-06 Enc Pulse Num into the Encoder pulse Standard (E.g.
1024).
c. Set DRV-09 Control Mode to Vector (sensored vector operating mode).
d. Set DRV-06 Cmd Source (operating command source), DRV-07 Freq Ref
Src (Frequency command source), DRV-03 Acc Time (acceleration time)
and DRV-04 Dec Time (deceleration time) respectively.
Step 3. Master/Slave Motor tuning
a. Read the Motor’s nameplate to input BAS-11 Pole Number (number of
motors’pole), BAS-12 Rated Slip (Motor rated slip RPM), BAS-13 Rated
Curr (Motor rated current), BAS-15 Rated Volt (Motor rated voltage), BAS-
16 Efficiency (Motor efficiency) and BAS-19 AC Input Volt (inverter Input
voltage).
b. You may select All (rotating tuning) or All StdStl (static tuning) from BAS-
20 Auto Tuning. In case that the motor cannot be rotated during the tuning
because of excessive load is placed to the motor, select All StdStl (static
tuning). However, rotating tuning shows relatively better performance than
static tuning and any value close to actual motor integral shall be
calculated.

14
Step 4. Set the external break control function
If BR Control is set from OUT-31~32(Relay1, 2) and OUT-33(Q1
Define), it is possible to use an applicable contact output as
external break control. For external break control function, set the
function from ADV-41(BR Rls Curr)~ADV-47(BR Eng Fr).
Step 5. Set the synchronization operating mode (Applicable
only to slave inverters)
Set APP-01 App Mode to Synchro. Henceforth, you may select a
relevant parameter to synchronization operating from SYN Group.
Step 6. Check the direction of Encoder pulse of the
master/slave inverter
Especially, for position sync operating, the direction of the master
inverter and that of the slave inverter shall be corresponding. Here,
it is assumed that it rotates counterclockwise (CCW) when APO-08
Enc Monitor pulse increases (+) and the motor axis is seen from
the front during the forward (FWD) operating.
a. Set SYN-21 Sync Mode to 0: SPD Ctrl for the slave inverter. Forward
(FWD) operating command shall be simultaneously made in low speed of
approximately 5Hz for the master and slave inverter. When monitoring the
pulse of the Slave inverter’s APO-08 Enc Monitor, check if the pulse
increases. If it decreases, exchange MA_A with MA_B and vice versa in
the applicable Slave Synchronization option terminal block wiring.

5 Position Sync Operating
15
5. Position Sync Operating
The master’s load axis position and many slaves’load axis position
are synchronized to operate. The master inverter does not need
any synchronization option card while the slave inverter uses
synchronization option cards to follow the master inverter position.
Since the slave follows the master’s encoder position pulse, the
Position Sync operating needs to be much more sophisticate than
the Speed Sync operating.
In actual, the slave inverter is controlled when the deviation
between the master and the slave position is within about 2 degree
(= Pi/90 rad) during 1800rpm steady-state operating.

SYN-31 SPD Lpf Gain
The Return Pulse Output of the master inverter will be inputted as
the master pulse of the slave inverter’s synchronization option card.
It is possible to set low-pass filter gain for the speed (rpm) decided
by its master pulse and make it less sensitive to noise. As a
bigger value is given, the effect of removing noise becomes more
significant but, the speed response of the save inverter becomes
lower.

5 Position Sync Operating
20
During the Position Sync operating, the master speed (rpm) that
has been low-pass filtered is the input of SYN-33 POS FF Gain, the
position controller’s feed forward gain.
SYN-32 SPD Limit
It limits to the slave inverter’s output speed(rpm).
SYN-33 POS FF Gain
It is the position controller’s feed forward gain. By forward
compensating the master’s current speed, it can increase the
response of the Position Sync operating.
SYN-35 POS P Gain
SYN-36 POS I Gain
SYN-37 POS D Gain
It is the PID controller’s P/I/D gain for Position Sync.
SYN-38 POS I Limit
It limits the PID controller’s Output for Position Sync as the
following equation. Therefore, any wind-up due to integral
operation can be prevented.
SYN-39 POS PIDout Scl
It adjusts the position PID controller’s output scale. If 100% is set,
100% of the position PID controller Output while only 10% of the
position PID controller Output will be outputted if 10% is set.
SYN-40 POS PIDout LPF
It is possible to set low pass filter gain to the position PID controller
Output. As a bigger set value is given, the position PID controller
Output will become more stable but, its response will be lower.
Except special cases, set it to an appropriate value(Less than
about 50ms).
