Page 4: General
Motortronics 1 About the Motortronics ABC Series General The ABC Series is a solid state DC injection brake for stopping three- phase AC induction motors. This full-wave DC brake design offers smooth, low peak level braking for quiet, steady operation and optimal performance. - Page 5 Motortronics 1.3.1 Standard Duty Sizing Applying an ABC Series brake that is rated for <115% of the FLA (Full Load Amp) rating of the motor allows maximum length of braking time without exceeding the thermal capacity of the stator windings. Since current is controlled by the ABC Series throughout the braking cycle, braking torque will vary as the motor circuit impedance decreases with speed.

Page 6: Applications
Motortronics Applications The ABC Series electronic brake is ideal for machine and process equipment control applications for efficiency, increased safety, and reduced equipment maintenance costs. Among the benefits: Efficiency is improved because you no longer have to wait through long coast-to-stop times for blade changes, batch loading, or maintenance shutdowns. -
Page 7: Abc Model Numbers, Ratings And Dimensions
1. Never exceed the Full Load Amp rating of the motor without checking the motor manufacturer's data with regards to appropriateness of the application and duty cycle. 2. If duty cycle is not known, Motortronics recommends using the Extra Duty Brake since braking current can be adjusted down to meet the actual load requirements. - Page 8 Motortronics N4/12 Outline: ABC-50/100-E N4/12 Outline: ABC-200-E Page 7 Phone: 800.894.0412 - Fax: 888.723.4773 - Web: www.clrwtr.com - Email: info@clrwtr.com...

Page 13: Operation
Motortronics 2 Operation Sequence of Operation The ABC Series brake becomes "Armed" when the motor starter turns "On” and then braking occurs when the starter is turned "Off". An Operator Interface Module has two large LEDs to indicate "Braking" or "Fault"... - Page 14 Motortronics 2.1.3 “Braking” The ABC Series will enter the braking mode when the motor is given a stop command after being "Armed" (see "JOG / ARMED" above). To prevent damaging current spikes, a factory programmed delay allows the existing motor magnetic field to decay before DC is applied (see section 5.1). During the "BRAKING" mode, a set of N.C.

Page 15: Fault Conditions
Motortronics Fault Conditions The “FAULT” LED will illuminate when any of the following conditions occur: 2.2.1 “Disabled” The "DISABLED" mode is activated when the ABC Series receives a command on the Brake Disable input (a N.O. dry contact at TB1) (see section 4.3.2). This mode can be used to remove the electronic brake from the system, and is useful in applications that only require braking at certain times during the process and during system setup. -
Page 16: Mechanical Brake Control
Motortronics Mechanical Brake Control The ABC Series includes a Mechanical Brake Release Relay that can be utilized to control an electro- mechanical brake coil. This relay has a Form “A” contact (1 N.O.) that changes state as follows (see section 4.3.4):... -
Page 17: Installation
Motortronics 3 Installation Receiving and Unpacking Upon receipt of the product you should immediately do the following: • Carefully unpack the unit from the shipping carton and inspect it for shipping damage. • Verify that the model number on the unit matches your purchase order. -
Page 18: Wiring
Motortronics 4 Wiring Introduction • Installation of the brake unit should be done by properly qualified personnel. • Check local and other applicable codes to ensure that all installation requirements are met prior to operation. • Prior to beginning the installation, verify that the motor and brake unit have the same voltage ratings. - Page 19 Motortronics 4.2.1 Line Power Connections Connect the line leads to the input terminals L1 and L2 provided on the unit. The line power must be supplied from a source with suitable Short Circuit Protective Devices (SCPD) conforming to local and national electric codes.
- Page 20 Motortronics 4.2.2 Load Power Connections Connect the motor leads to the output terminals T1 and T2 provided on the unit. The unit will operate on either a Wye or a Delta connected motor. An additional control wire must be run from motor lead T3 of the starter to the voltage sensing circuit of the ABC Series.
-
Page 21: Control Connections
Motortronics Control Connections Control wire should be run in a separate conduit from power lines (twisted, shielded cable should be adequate). Whenever possible, conduits containing control and power conductors should cross at right angles to each other. Control connections are made to terminal blocks mounted on the printed circuit boards inside the unit case. - Page 22 Motortronics 4.3.2 Brake Disable Input Disables electronic braking functions before, during, or after operation (refer to section 2.2.1). To utilize this feature, wire a N.O. dry contact to TB1 terminals 3 and 4 on the logic board. The disable feature will activate as long as the contact is closed, and will resume operation sequence only when the disable command is released (i.e.
- Page 23 Motortronics 4.3.3 Interlock Contacts The ABC Series unit must be interlocked with the motor starter coil circuit to disable the motor starter during the braking cycle for proper operation (refer to 2.1.3). Two sets of "FORM C" contacts are provided on TB2 on power board to interlock the motor starter with the brake.

Page 24: Adjustements
Motortronics 5 Adjustments Time Adjustment Procedures Time settings for "Jog Time" and "Brake Time" are adjusted by use of dip switches on the front mounted Operator Interface Module. Time settings are in seconds (set in binary code). Each switch denotes a binary digit from 1 - 7 positions, totalling 127 seconds maximum when all are switched to the "On"... -
Page 25: Brake Time Adjustment
Motortronics Brake Time Setting Factory Setting: 7 seconds The brake time is programmable from 1 to 127 seconds. Set the switches marked "Brake Time" to the brake time required. Typical brake time settings should be 1/2 of the load's coast-to-stop time or less, as necessary. - Page 26 Motortronics Application Specific Adjustments These settings are factory preset to provide optimum performance in a wide variety of applications, and should not be changed unless the user is specifically aware of the risks and consequences (contact factory for details). Brake On Delay (Switch SW1) This DIP switch controls the amount of time that the ABC Series brake waits prior to applying DC current to the motor windings in order to allow the magnetic field to decay.
