1.3 Product Overview
A frequency converter is an electronic motor controller
that converts AC mains input into a variable AC waveform
output. The frequency and voltage of the output are
regulated to control the motor speed or torque. The
frequency converter can vary the speed of the motor in
response to system feedback, such as position sensors on a
conveyor belt. The frequency converter can also regulate
the motor by responding to remote commands from
external controllers.
In addition, the frequency converter monitors the system
and motor status, issues warnings or alarms for fault
conditions, starts and stops the motor, optimizes energy
efficiency, and offers many more control, monitoring, and
efficiency functions. Operation and monitoring functions
are available as status indications to an outside control
system or serial communication network.

2.4.1 Requirements
WARNING
EQUIPMENT HAZARD!
Rotating shafts and electrical equipment can be hazardous.
All electrical work must conform to national and local
electrical codes. It is strongly recommended that instal-
lation, start up, and maintenance be performed only by
trained and qualified personnel. Failure to follow these
guidelines could result in death or serious injury.
CAUTION
WIRING ISOLATION!
Run input power, motor wiring and control wiring in three
separate metallic conduits or use separated shielded cable
for high frequency noise isolation. Failure to isolate power,
motor and control wiring could result in less than
optimum frequency converter and associated equipment
performance.
For your safety, comply with the following requirements.
•
Electronic controls equipment is connected to
hazardous mains voltage. Extreme care should be
taken to protect against electrical hazards when
applying power to the unit.
•
Run motor cables from multiple frequency
converters separately. Induced voltage from
output motor cables run together can charge
equipment capacitors even with the equipment
turned off and locked out.
Overload and Equipment Protection
•
An electronically activated function within the
frequency converter provides overload protection
for the motor. The overload calculates the level of
increase to activate timing for the trip (controller
output stop) function. The higher the current
draw, the quicker the trip response. The overload
provides Class 20 motor protection. See
8 Warnings and Alarms for details on the trip
function.
•
Because the motor wiring carries high frequency
current, it is important that wiring for mains,
motor power, and control are run separately. Use
metallic conduit or separated shielded wire.
Failure to isolate power, motor, and control
wiring could result in less than optimum
equipment performance.
•
All frequency converters must be provided with
short-circuit and over-current protection. Input
fusing is required to provide this protection, see
Illustration 2.5. Fuses must be provided by the
installer as part of installation. See maximum fuse
ratings in 10.3 Fuse Tables.
Illustration 2.5 Fuses
Wire Type and Ratings
•
All wiring must comply with local and national
regulations regarding cross-section and ambient
temperature requirements.
•
GE recommends that all power connections be
made with a minimum 75°C rated copper wire.
•
See 10.1 Power-dependent Specifications for
recommended wire sizes.
2.4.2 Earth (Grounding) Requirements
WARNING
GROUNDING HAZARD!
For operator safety, it is important to ground drive
properly in accordance with national and local electrical
codes as well as instructions contained within these
instructions. Ground currents are higher than 3,5mA.
Failure to ground drive properly could result in death or
serious injury.
NOTE
It is the responsibility of the user or certified electrical
installer to ensure correct grounding (earthing) of the
equipment in accordance with national and local electrical
codes and standards.
•
Follow all local and national electrical codes to
ground electrical equipment properly
•
Proper protective grounding for equipment with
ground currents higher than 3,5mA must be
established, see Leakage Current (>3,5mA)
•
A dedicatedground wire is required for input
power, motor power and control wiring
Installation AF-650 GP Operating Instructions
12

•
Use the clamps provided with on the equipment
for proper ground connections
•
Do not ground one drive to another in a “daisy
chain” fashion
•
Keep the ground wire connections as short as
possible
•
Use of high-strand wire to reduce electrical noise
is recommended
•
Follow motor manufacturer wiring requirements
2.4.2.1 Leakage Current (>3,5mA)
Follow national and local codes regarding protective
earthing of equipment with a leakage current > 3,5mA.
Drive technology implies high frequency switching at high
power. This will generate a leakage current in the earth
connection. A fault current in the drive at the output
power terminals might contain a DC component which can
charge the filter capacitors and cause a transient earth
current. The earth leakage current depends on various
system configurations including RFI filtering, screened
motor cables, and drive power.
EN/IEC61800-5-1 (Power Drive System Product Standard)
requires special care if the leakage current exceeds 3,5mA.
Earth grounding must be reinforced in one of the
following ways:
•
Earth ground wire of at least 10mm
2
•
Two separate earth ground wires both complying
with the dimensioning rules
See EN 60364-5-54 § 543.7 for further information.
Using RCDs
Where residual current devices (RCDs), also known as earth
leakage circuit breakers (ELCBs), are used, comply with the
following:
Use RCDs of type B only which are capable of
detecting AC and DC currents
Use RCDs with an inrush delay to prevent faults
due to transient earth currents
Dimension RCDs according to the system configu-
ration and environmental considerations
2.4.2.2 Grounding Using Shielded Cable
Earthing (grounding) clamps are provided for motor wiring
(see Illustration 2.6).
Illustration 2.6 Grounding with Shielded Cable
2.4.3 Motor Connection
WARNING
INDUCED VOLTAGE!
Run output motor cables from multiple frequency
converters separately. Induced voltage from output motor
cables run together can charge equipment capacitors even
with the equipment turned off and locked out. Failure to
run output motor cables separately could result in death
or serious injury.

•
Ground the cable in accordance with grounding
instructions provided in 2.4.2 Earth (Grounding)
Requirements
•
All frequency converters may be used with an
isolated input source as well as with ground
reference power lines. When supplied from an
isolated mains source (IT mains or floating delta)
or TT/TN-S mains with a grounded leg (grounded
delta), set SP-50 RFI Filter to OFF. When off, the
internal RFI filter capacitors between the chassis
and the intermediate circuit are isolated to avoid
damage to the intermediate circuit and to reduce
earth capacity currents in accordance with IEC
61800-3.
2.4.5 Control Wiring
•

2.4.5.3 Wiring to Control Terminals
Control terminal connectors can be unplugged from the
drive for ease of installation, as shown in Illustration 2.10.
1. Open the contact by inserting a small screwdriver
into the slot above or below the contact, as
shown in Illustration 2.12.
2. Insert the bared control wire into the contact.
3. Remove the screwdriver to fasten the control wire
into the contact.
4. Ensure the contact is firmly established and not
loose. Loose control wiring can be the source of
equipment faults or less than optimal operation.
See 10.1 Power-dependent Specifications for control terminal
wiring sizes.
See 6 Application Set-Up Examples for typical control wiring
connections.

2.4.5.4 Using Screened Control Cables
Correct screening
The preferred method in most cases is to secure control
and serial communication cables with screening clamps
provided at both ends to ensure best possible high
frequency cable contact.
If the earth potential between the frequency converter and
the PLC is different, electric noise may occur that will
disturb the entire system. Solve this problem by fitting an
equalizing cable next to the control cable. Minimum cable
cross section: 16 mm

.
50/60Hz ground loops
With very long control cables, ground loops may occur. To
eliminate ground loops, connect one end of the screen-to-
ground with a 100nF capacitor (keeping leads short).
Avoid EMC noise on serial communication
This terminal is connected to earth via an internal RC link.
Use twisted-pair cables to reduce interference between
conductors. The recommended method is shown below:
Alternatively, the connection to terminal 61 can be
omitted:

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.

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:
•
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.
