For example:
Condition 1: Suppose the max. pressure holding speed of the master is 50 rpm/min., the max. speed of the master
is 2000 rpm/min., and the max. speed of the slave is 2000 rpm/min.
Condition 2: At pressure hoding, the master works and the slave stops.
Condition 3: To ensure ow linearity, The master is over 100 rpm/min. and the slave keeps the same speed.
That is, when the master pump is below 50 rpm/min., the slave pump stops running. When the master pump is
above 100 rpm/min, the master pump and the slave pump keep the same speed.
The speed reference of the master pump is 0% to 100%. You can set A3-32 to A3-37 to get the three-point curve to
make the slave pump respond to the speed reference as follows:
A3-32, A3-33 = Slave pump input reference: 50 rpm/min., slave response reference: 0 rpm/min. = 2.5%, 0.0%
A3-34, A3-35 = Slave pump input reference: 100 rpm/min., slave response reference: 100 rpm/min. = 5.0%, 5.0%
A3-36, A3-37 = Slave pump input reference: 2000 rpm/min., slave response reference: 2000 rpm/min. = 100%,
100%
