Installation
Avoid EMC noise on serial communication
This terminal is connected to ground via an internal RC
link. Use twisted-pair cables to reduce interference
between conductors. The recommended method is in
Illustration 2.16:
1 2
Minimum 16 mm (6 AWG)
2 Equalizing cable

Alternatively, the connection to terminal 61 can be
omitted:

2.5.5.5 Control Terminal Functions

Frequency converter functions are commanded by
receiving control input signals.
•
Each terminal must be programmed for the
function it is supporting in the parameters
associated with that terminal. See Table 2.5 for
terminals and associated parameters.
•
It is important to confirm that the control
terminal is programmed for the correct function.
See chapter 4 User Interface for details on
accessing parameters and chapter 5 About
Programming for details on programming.
•
The default terminal programming is intended to
initiate frequency converter functioning in a
typical operational mode.

NOTICE
Some option cards available for the unit may cover these
switches and must be removed to change switch
settings. Always remove power to the unit before
removing option cards.

2.5.5.7 Terminal 37

Terminal 37 Safe Torque Off function
The AF-650 GP is available with Safe Torque Off
functionality via control terminal 37. Safe torque off (STO)
disables the control voltage of the power semiconductors
of the frequency converter output stage which in turn

Analog input terminals 53 and 54 can select
either voltage (-10 V to 10 V) or current (0/4–20
mA) input signals.
Remove power to the frequency converter before
changing switch positions.
Set switches A53 and A54 to select the signal
type. U selects voltage, I selects current.
The switches are accessible when the keypad has
been removed (see Illustration 2.18).
Terminal 53 default is for a speed reference signal
in open loop set in parameter DR-61 Terminal 53
Switch Setting.
Terminal 54 default is for a feedback signal in
closed loop set in parameter DR-63 Terminal 54
Switch Setting.
