Terminal [FM1], [FM2] (Function selection)
By setting “17: Master-follower angle deviation” for F31 and F61, the master-follower angle deviation is output to
analog output. An example when voltage output is set is shown in the following diagram.

Fig. 5.3-40 Master-follower angle deviation monitoring with analog output voltage
To perform master-follower operation, select a control mode with speed sensor (F42 = 3, 4 or 6). Usually, select “V/f
control with speed sensor” (F42 = 3).
Speed Control
(Speed command filter, Speed detection filter, P (Gain), I (Integral time), FF(Gain))
These function codes set up the speed control response. Refer to d01.
PG option Ch2 (Feedback input)
(Pulse input method), (Encoder pulse count), (Pulse scaling factor 1), (Pulse scaling factor 2),
These function codes specify the speed feedback input under vector control with speed sensor (F42 = 3, 4 or 6).
Refer to d14 to d17.
PG option Ch2 (Feedback input) (Filter time constant)
Sets the filter time constant for feedback input. The larger the time constant, the slower the response. Specify the
proper filter time constant taking into account the response speed of the machine (load). If the pulse is lower and
frequency command fluctuates, set larger time constant.
