Installation

2.4.5.5 Control Terminal Functions

Drive functions are commanded by receiving control input
signals.
•
Each terminal must be programmed for the
function it will be supporting in the parameters
associated with that terminal. See Table 2.2 for
terminals and associated parameters.
•
It is important to confirm that the control
terminal is programmed for the correct function.
See 4 User Interface for details on accessing
parameters and for details on programming.
•
The default terminal programming is intended to
initiate drive functioning in a typical operational
mode.

2.4.5.6 Terminal 53 and 54 Switches

•
Analog input terminals 53 and 54 can select
either voltage (-10 to 10V) or current (0/4-20mA)
input signals
•
Remove power to the drive 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 2.13). Note that
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.
•
Terminal 53 default is for a speed reference signal
in open loop set in DR-61 Terminal 53 Switch
Setting
•
Terminal 54 default is for a feedback signal in
closed loop set in DR-63 Terminal 54 Switch

2.4.5.7 Terminal 37

Terminal 37 Safe Stop Function
The AF-650 GP and is available with safe stop functionality
via control terminal 37. Safe stop disables the control
voltage of the power semiconductors of the drive output
stage which in turn prevents generating the voltage
required to rotate the motor. When the Safe Stop (T37) is
activated, the drive issues an alarm, trips the unit, and
coasts the motor to a stop. Manual restart is required. The
safe stop function can be used for stopping the drive in
emergency stop situations. In the normal operating mode
when safe stop is not required, use the frequency
converter's regular stop function instead. When automatic
restart is used – the requirements according to ISO
12100-2 paragraph 5.3.2.5 must be fulfilled.
Liability Conditions
It is the responsibility of the user to ensure personnel
installing and operating the Safe Stop function:
•
•
•
User is defined as: integrator, operator, servicing,
maintenance staff.
