138 Chapter 6 Parameter description
F5.14 Synchronous motor counter
EMF constant
Range：0.1~6553.5V【300.0V】
Synchronous motor stator resistance is defined as half of the resistance
of any two lines among U V W.
Synchronous motor counter EMF constant is defined as voltage of any
two lines among UVW when the motor is driven to rated frequency (F0.10).
F5.11~F5.14 are the main parameters that affect the drive control
performance. The values are automatically filled and saved accordingly
after tuning operation until next time modification or next time parameter
tuning.
Note: Static tuning can only acquire F5.11~F5.13 values, while dynamic
tuning can acquire all 4 values for F5.11~F5.14.
6.7 Input terminals group (F6)
F6.00 Terminal Command mode Range: 0～3【0】
This parameter defines four different control modes that control the drive
operation through external terminals.
0: Two-wire mode 1
This mode is the most commonly used two-line mode. The
forward/reverse rotation of the motor is decided by the commands of
FWD and REV terminals, as shown in Fig.6-13.
Fig.6-13 Two-wire mode 1
1: Two-wire mode 2
In this mode, both function RUN (Run command) and F/R (Running
direction) are used: If RUN is enabled, the drive will startup. If F/R is
selected but disabled, the drive will run forward. If F/R is selected and
