.Related parameter settings:
1. Frequency reference selction:00-05=4 (Pulse input ) 。
2.Pulse input’s function selection:03-30=0 (Frequency command) 。
3.Pulse input scale:03-31 (set the number of pulse in Hz to equal to the maximum
output frequency, 01-02)
4.Pulse input gain:03-32 (Set the input gain of the pulse frequency set by 03-31)
5.Pulse input bias:03-33 (Set the input bias of the pulse frequency set by 03-31)
6.Pulse input’s filter time:03-34 (if the pulse input is instable due to the interference,
please increase the set value.)
. Use the forward and reverse commands of multi-function digital input to change the
rotation orientation.
. If high accuracy is required, you can apply the SV or V / f + PG control mode.
Example B: The connection operation of 2 inverters
. As to use two inverters for "tracking" or synchronization operation, please refer to
Figure 4.3.32.

.INV 1’s related parameter setting:
1. Frequency reference input::
Case 1: Set the parameter associated with the pulse input to the same as the
previous example, so as to use pulse input (for example, the master PG, etc.) to
run INV 1.
Case 2: Use 00-05 to select the main frequency reference so as to use the analog
frequency reference to run INV 1.
2. Frequency reference pulse output:
a. Pulse output function selection: 03-35=1 (the output frequency reference from the
pulse output terminal PO).
b. Pulse output scale : 03-36(when the operation is in full speed, set the number of
