What These Instructions Contain

How Dynamic Braking Works

These instructions contain the necessary information to select, configure
and install dynamic braking. By completing Selecting a Chopper Module
and the Maximum Dynamic Brake Resistance first you will be able to
determine:

1. Whether or not dynamic braking is required for your application.

2. If dynamic braking is required, the rating and quantity of chopper

modules required as well as the size and type of braking resistors
required.

When an induction motor’s rotor is turning slower than the synchronous
speed set by the drive’s output power, the motor is transforming electrical
energy obtained from the drive into mechanical energy available at the drive
shaft of the motor. This process is referred to as motoring. When the rotor
is turning faster than the synchronous speed set by the drive’s output power,
the motor is transforming mechanical energy available at the drive shaft of
the motor into electrical energy that can be transferred back into the utility
grid. This process is referred to as regeneration.

Most AC PWM drives convert AC power from the fixed frequency utility
grid into DC power by means of a diode rectifier bridge or controlled SCR
bridge before it is inverted into variable frequency AC power. Diode and
SCR bridges are cost effective, but can only handle power in the motoring
direction. Therefore, if the motor is regenerating, the bridge cannot conduct

1336-5.65 — March, 2007

Heavy Duty Dynamic Braking 3

the necessary negative DC current, the DC bus voltage will increase and
cause a Bus Overvoltage trip at the drive.

Expensive bridge configurations use SCRs or transistors that can transform
DC regenerative electrical energy into fixed frequency utility electrical
energy. A more cost effective solution is to provide a Transistor Chopper
on the DC Bus of the AC PWM drive that feeds a power resistor which
transforms the regenerative electrical energy into thermal energy. This is
generally referred to as Dynamic Braking.

How the Chopper Module Works

Figure 1 shows a simplified schematic of a Chopper Module with Dynamic

Brake Resistor. The Chopper Module is shown connected to the positive
and negative conductors of an AC PWM Drive. The two series connected
Bus Caps are part of the DC Bus filter of the AC Drive.

A Chopper Module contains five significant power components:

Protective fuses are sized to work in conjunction with a Crowbar SCR.
Sensing circuitry within the Chopper Transistor Voltage Control determines
if an abnormal conditions exist within the Chopper Module, such as a
shorted Chopper Transistor. When an abnormal condition is sensed, the
Chopper Transistor Voltage Control will fire the Crowbar SCR, shorting
the DC Bus, and melting the fuse links. This action isolates the Chopper
Module from the DC Bus until the problem can be resolved.

The Chopper Transistor is an Insulated Gate Bipolar Transistor (IGBT). The
Chopper Transistor is either ON or OFF, connecting the Dynamic Brake
Resistor to the DC Bus and dissipating power, or isolating the resistor from
the DC Bus. There are several transistor ratings that are used in the various
Chopper Module ratings. The most important rating is the collector current
rating of the Chopper Transistor that helps to determine the minimum ohmic
value used for the Dynamic Brake Resistor.

Chopper Transistor Voltage Control (hysteretic voltage comparator)
regulates the voltage of the DC Bus during regeneration. The average values
of DC Bus voltages are:

• 375V DC (for 230V AC input)

• 750V DC (for 460V AC input)

• 937.5V DC (for 575V AC input)
Voltage dividers reduce the DC Bus voltage to a value that is usable in signal

circuit isolation and control. The DC Bus feedback voltage from the voltage
dividers is compared to a reference voltage to actuate the Chopper
Transistor.

The Freewheel Diode (FWD), in parallel with the Dynamic Brake Resistor,
allows any magnetic energy stored in the parasitic inductance of that circuit
to be safely dissipated during turn off of the Chopper Transistor.

How to Select a Chopper Module and Dynamic Brake Resistor

As a rule, a Chopper Module can be specified when regenerative energy is
dissipated on an occasional or periodic basis. In general, the motor power
rating, speed, torque, and details regarding the regenerative mode of
operation will be needed in order to estimate what Chopper Module rating
and Dynamic Brake Resistor value to use. If a drive is consistently operating
in the regenerative mode of operation, serious consideration should be given
to equipment that will transform the electrical energy back to the fixed
frequency utility.

In order to select the appropriate Chopper Module and Dynamic Brake
Resistor for your application, the following data must be calculated.

Peak Regenerative Power of the Drive (Expressed in watts of power.)
This value is used to determine:

• The minimum current rating of the Chopper Module
Choose the actual current rating from the selection tables.

• The estimated maximum ohmic value of the Dynamic Brake Resistor
If this value is greater than the maximum imposed by the peak
regenerative power of the drive, the drive can trip off due to transient
DC Bus overvoltage problems.

Minimum Dynamic Brake Resistance

If a Dynamic Brake Resistance value that is less than the minimum imposed
by the choice of the Chopper Module is applied, damage can occur to the
Chopper Transistor.

Dynamic Brake Resistor’s Allowable Ohmic Value Range

(Use the Chopper Module current rating to determine this range.)
These values range between the minimum value set by the Chopper

Transistor current rating and the maximum value set by the peak
regenerative power developed by the drive in order to decelerate or satisfy
other regenerative applications.

Wattage Rating of the Dynamic Brake Resistor

This rating is estimated by applying what is known about the drive’s
motoring and regenerating modes of operation. The average power
dissipation of the regenerative mode must be estimated and the wattage of
the Dynamic Brake Resistor chosen to be greater than the average
regenerative power dissipation of the drive.

Dynamic Brake Resistors with large thermodynamic heat capacities,
defined as thermal time constants less than 5 seconds, are able to absorb a
large amount of energy without the temperature of the resistor element
exceeding the operational temperature rating. Thermal time constants in
the order of 50 seconds and higher satisfy the criteria of large heat capacities
for these applications. If a resistor has a small heat capacity, the temperature
of the resistor element could exceed maximum temperature limits during
the application of pulse power to the element.

Selecting a Chopper Module and the Maximum Dynamic Brake Resistance

The following calculations are demonstrated using The International
System of Units (SI).

• Power rating from motor nameplate in watts, kilowatts, or horsepower

• Speed rating from motor nameplate in rpm or rps (radians per second)

• Motor inertia and load inertia in kg-m

function of time for a particular cyclic application that is periodic over t

Calculate Application Values

Use the Application Information to calculate the necessary values to choose
an acceptable Chopper Module and Dynamic Brake Resistor.

Rated Power of Motor = 100 HP × 746 = 74.6 kW

This information is given and must be known before the calculation process
begins. If this rating is given in horsepower, convert to watts before using
in the equations.

Rated Speed = 1785 RPM = 2π × 1785/60 = 186.93 Rad/s = ω

This information is given and must be known before the calculation process
begins. If this rating is given in RPM, convert to radians per second before
using in the equations.

Total Inertia = 9.61 kg-m2 = J

T

If this value is given in lb-ft2 or Wk2, convert to kg-m2 before using in the
equations. Total inertia is given and does not need further calculations as
outlined in Step 2.

This is the result of calculating the average power dissipation as outlined
in Step 8. Verify that the power rating of the Dynamic Brake Resistor chosen
in Step 7 is greater than the value calculated in Step 8. Note that the actual
resistor wattage rating is much greater than what is needed. The type
T10F4R2K97 assembly is the best choice based on resistance and wattage
values.

ATTENTION: Electric Shock can cause injury or death.
Remove all power before working on this product.

!

For all chopper module ratings, DC brake power is supplied
from the drive DC Bus.

Hazards of electrical shock exist if accidental contact is made
with parts carrying bus voltage. A DC power indicator on the
brake enclosures provides visual indication that bus voltage
is present. Before proceeding with any installation or
troubleshooting activity, allow at least one minute after input
power has been removed for the bus circuit to discharge. Bus
voltage should be verified by using a voltmeter to measure
the voltage between the +DC and -DC terminals on the drive
power terminal block. Do not attempt any servicing until the
DC power indicating light has extinguished and bus voltage
has been verified to be zero volts.

1336-5.65 — March, 2007

Mounting Requirements

IMPORTANT: The National Electrical Code (NEC) and
local regulations govern the installation and wiring of the
brake chopper modules, dynamic braking resistors and
enclosure selection. DC power wiring, AC power wiring,
control wiring and conduit must be chosen, sized and
installed in accordance with these codes and the
information supplied on the following pages.

Brake chopper modules must only be installed in the
vertical position. Select an enclosure and a location using
the guidelines below and on the following page.

Heavy Duty Dynamic Braking 25

Air Flow

(Front)

1. Allow a minimum clearance of 152.4 mm

(6 in.) Between brake modules inside an
enclosure and all other equipment including
the drive. All brake resistor banks should be
mounted external to the enclosure on a non
combustible surface.

2. If more than one module is required, all

modules must be mounted within 3.0 m (10 ft.)
of the drive. The wires used to connect each
module to the drive must be the same length.
Resistors must be located within 30 m (100 ft.)
of the chopper module. The minimum distance
between each resistor bank and all other
enclosures or equipment is application
dependent and must be determined by the user.

Setup

Heavy Duty Dynamic Braking

1336 and 1336VT Parameter Settings

Parameter 11 — Decel Frequency Hold — must be set to OFF when
dynamic braking is installed. Refer to your 1336 or 1336VT Programming
Manual for programming procedures and record the changes for future
reference.

ATTENTION: Each brake chopper module contains a
thermostat to guard against overheating and component

!

damage.
If the duty cycle, torque setting and/or ambient temperature

exceeds the specifications listed in this publication, the
thermostat is designed to trip and disable the brake modules
until components cool to rated temperature. During the
cooling period, only 10% braking torque will be available to
the motor.

If reduced braking torque represents a potential hazard to
personnel, auxiliary stopping methods must be considered
in the machine and/or control circuit design.

1336IMPACT Parameter Settings

When dynamic braking is installed:

• Parameter 76 [Regen Power Lim] typically should be set to its factory default
of “-200.0%”. A lower Regen Power Lim may be required to protect the
load during decel.

• Set Bit 10 of Parameter 13 [Bus Options].

Refer to your 1336IMPACT User Manual for programming procedures and
record the changes for future reference.

1336FORCE Parameter Settings

When dynamic braking is installed:

•A lower Regen Power Lim may be required to protect the load during decel.
Parameter 178 [Regen Power Lim] typically should be set to the required
negative % of torque.

• Clear Bit 11 of Parameter 88 [VP Flt/Warn Cfg].

Refer to your 1336FORCE User Manual for programming procedures and
record the changes for future reference.

1336PLUS and 1336PLUSII Parameter Settings

When dynamic braking is installed:

• Parameter 11 [Bus Limit En] must be set to “Disabled”.

• Braking for deceleration requires that the drive be programmed for
“Ramp-to-Stop”. Braking for overhauling loads may or may not be stop
mode specific. Program Parameters 10 and 52 per the application.

Refer to your 1336PLUS User Manual for programming procedures and
record the changes for future reference.

Brake Fault Contact Monitoring

Brake Fuses

Brake Module Jumper Settings

For all brake module ratings a fault contact has been provided to provide a
remote output signal. Should a brake fuse fail or the brake thermostat trip,
the brake fault contact will open. Interconnection wiring for remote brake
monitoring is provided in the Wiring Schemes section.

All brake modules are internally fused to protect brake components. When
replacing brake fuses, use only the type and size specified below.
