output pulse
. INV 2’s related parameter setting
1. Frequency reference input00-05=4 (Pulse input )
2. Function selection of pulse input03-30=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, generally set this value to the same value as 03-31 of INV
1)
4.Pulse input gain03-32Set the input gain of the pulse frequency set by 03-31.
when INV2 is geometric proportion, please adjust 03-32)。
5.Pulse input bias03-33Set the input bias of the pulse frequency set by 03-31.
When the bias setting of INV 2 has been set, please adjust 03-33)。
6.Pulse input’s filter time03-34(if the pulse input is instable due to the interference,
please increase the set value.)
Example C: The synchronized operation of using pulse input
Figure 4.3.33 The synchronized operation of using pulse input
. Apply the pulse signals of external pulse generator to the pulse input terminal PI of
multiple inverters for synchronization.
. Set 00-05 to 4 (pulse input frequency command), and set 03-30 to 0 (pulse input
terminal function as frequency command).
. By setting the corresponding parameter (03-00 to 03-07) to 32, specify any one of the
multi-function digital input terminals (S1 to S8) for synchronization command.
. Change the serial pulse received from pulse input (terminal PI) into a synchronized
frequency command so that the synchronization command (SYNC) ensures the
frequency reference can be executed. For the synchronization operation of using
pulse input, please refer to Figure 4.3.33.
