•
The default terminal programming is intended to
initiate drive functioning in a typical operational
mode.
3.4.5.6 Terminal 53 and 54 Switches
•
Analog input terminals 53 and 54 can select
either voltage (-10–10V) 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
). 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 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 adjustable
frequency drive’s regular stop function instead. When
automatic restart is used – the requirements under 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:
•
Read and understand the safety regulations
concerning health and safety/accident prevention
•
Understand the generic and safety guidelines
given in this description and the extended
description in the
Design Guide
•
Have a good knowledge of the generic and safety
standards applicable to the specific application
User is defined as: integrator, operator, servicing,
maintenance staff.
Standards
Use of safe stop on terminal 37 requires that the user
satisfies all provisions for safety including relevant laws,
regulations and guidelines. The optional safe stop function
complies with the following standards.
EN 954-1: 1996 Category 3
IEC 60204-1: 2005 category 0 – uncontrolled stop
IEC 61508: 1998 SIL2
IEC 61800-5-2: 2007 – safe torque off (STO)
function
IEC 62061: 2005 SIL CL2
ISO 13849-1: 2006 Category 3 PL d
ISO 14118: 2000 (EN 1037) – prevention of
unexpected start-up
The information and instructions of the instruction manual
are not sufficient for a proper and safe use of the safe stop
functionality. The related information and instructions of
the relevant
Design Guide
must be followed.
