Unavailable Function Codes
During master-follower operation, the following functions are not available.
F16 Frequency Limiter (Low)
C30 C01 to C04:Jump Frequency
Selecting “Vector control for induction motor with speed sensor” (F42 = 6) disables the settings of the following
functions during master-follower operation, as well as making the above functions unavailable.
F07, F08 Acceleration Time 1/Deceleration Time 1
E10, E11 Acceleration Time 2/Deceleration Time 2
E12, E13 Acceleration Time 3/Deceleration Time 3
E14, E15 Acceleration Time 4/Deceleration Time 4
F24 Starting frequency (Holding time)
F39 Stop frequency (Holding time)
During master-follower operation, the following control should be disabled (H18 = 0, J01 = 0).
H18 Torque control
J01 PID control
Configuring Function Codes
To perform master-follower operation, be sure to select a control mode with speed sensor (F42 = 3, 4 or 6) and
configure the function codes given in this section.

Data setting for master-follower operation
F01 Frequency setting 1
C30 Frequency setting 2
Select the pulse train input (F01/C30 = 12) as a reference command source.
Switching between master-follower operation and individual operation is possible using the “
Hz2/Hz1 ” terminal
command (see Figure 5.3-25 and Figure 5.3-26). The switching example is given below.
(Example) Turning terminal [X1] ON for individual 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 master-follower operation and individual 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 to apply after switching.
F07/E10/E12/E14 Acceleration Time
F08/E11/E13/E15 Deceleration Time
Also in master-follower operation, the inverter controls the output frequency according to the acceleration
/deceleration time as usual. Set the acceleration/deceleration time as short as possible. Be careful that, setting the
acceleration/deceleration time longer than that of the reference inverter loses the following capability of the
follower motor.
Selecting “Vector control for induction motor with speed sensor” (F42 = 6) ignores the acceleration
/deceleration times specified by the function codes, running the motor with the acceleration/deceleration
time 0.0 s.
