2-18 Installation and Wiring
When connecting a single input such as Run, Stop, Reverse or Preset Speeds to
multiple drives, it is important to connect the commons (TB3-7) together for all
drives. If they are to be tied into another common (such as earth ground or separate
apparatus ground) only one point of the daisy chain of TB3-7 should be connected.
Predicting actual performance given the variety of installation possibilities is
difficult, however, up to five drives with two meters of cable between have been
tested without problems.
Typical Multiple Drive Input Connections Figure 2.15
Configurable Relay Output Contacts (P47 Settings)
You can configure the drive’s dry contact Form C output relay to change state based
on P47 - [Output Configure] setting and P48 - [Output Threshold] limits. See Chapter 5
for details.

Frequency Source Wiring
Analog Signal Follower Model
You can control the output frequency of the drive via the Control Terminal Block
(TB3) using the following methods.
Analog Frequency Sources
Important: Only one frequency source may be connected at a time. If more
than one reference is connected at the same time, an undetermined
frequency reference will result.
