Wiring
• Analog Output - Pulse
– Master/Slave (Leader/Follower)
– DO of Master to DI of Slave set for Pulsed Reference
– Use 0-Fmax 0-32,000 pulses, set max pulses to 32,000 use P
202 on master to match slope.
– Use P 215 on slave to match intercept.
Analog Output – Pulse
The diagram above shows another way to connect 2 drives together in a
Master/Slave (Leader/Follower) arrangement. This arrangement acts like an encoder and is
slightly more accurate, perhaps 0.2Hz being the maximum error over the 3 to 60Hz range.
In the diagram above, the pulsed reference signal, terminal 42 from the master drive
(1) is connected to a digital input terminal 17 of the slave drive (2). Terminal 17 or 29 can be
used, but it must be programmed for “Pulse Reference”. The common terminal 39 from the
master is attached to the common of the slave terminal 20. The square wave attached to
terminal 42 is used to indicate a pulsed output.
Parameter 319 in the master is set to “0-Fmax = 0-32000p”. Parameter 320 sets the
number of pulses, which is more accurate if increased to 32000. The slave in parameter 327
must have its pulses set to 32000, the same number placed in p 320 of the master. Ratios
may be set using these 2 parameters. Example: 2:1 ratio can be set up with 32000 set in p
320 in the master and 16000 set in p 327 in the slave.
