RIVE PTIONS In 1975, Bonitron began working with AC inverter drive specialists at synthetic fiber plants to develop speed control systems that could be interfaced with their plant process computers. Ever since, Bonitron has developed AC drive options that solve application issues associated with modern AC variable frequency drives and aid in reducing drive faults.

URPOSE AND COPE This manual is a user’s guide for the Model M3575R Resistive Braking Load Modules. It will provide the user with the necessary information to successfully install, integrate, and use the M3575R modules in any Motion Control System.
M3575R 1.4. YMBOL ONVENTIONS SED IN THIS ANUAL AND ON QUIPMENT Earth Ground or Protective Earth AC Voltage DC Voltage DANGER: Electrical hazard - Identifies a statement that indicates a shock or electrocution hazard that must be avoided. DANGER! DANGER: Identifies information about practices or circumstances that can lead to personal injury or death, property damage, or economic loss.
For applications where this condition occurs infrequently, dissipating the energy as heat through resistive braking control can be the most cost-effective solution. The Model M3575R series of braking products is designed to provide resistive loads for braking control in applications utilizing a standard AC drive with a fixed DC bus. These...

M3575R the units. The M3575R must ALWAYS be mounted with the rear surface of the unit to the mounting surface. Refer to Figure 3-1A for acceptable mounting orientation. NEVER mount a unit in a horizontal position with its side parallel to the mounting surface or floor as shown in Figure 3-1C.
I/O W 3.4.2. IRING The M3575R Resistive Load is equipped with an Over-Temp contact for use with existing drive or system interlock circuitry. Please refer to the system documentation for field control interlock connection details. When installing M3575R modules in parallel, it is recommended that the over-temperature contacts of these units be connected in series as shown in Figure 3-5.
User’s Manual PERATION The operation of the M3575R Resistive Load Module is passive in that there are no parameters or adjustments that can be made before or during operation. Please refer to the ratings charts in Tables 6-1 thru 6-4 in Section 6 and selection criteria for proper sizing considerations.

AINTENANCE AND ROUBLESHOOTING Repairs or modifications to this equipment are to be performed by certified personnel only. Any repair or modification to this equipment by personnel not approved by Bonitron will void any warranty remaining on this unit. 5.1. ERIODIC ESTING Monthly, look at surrounding surfaces for any discoloration or scorching.
M3575R 2. Verify that appropriate voltage input is present for fan power. Input voltage should be 115VAC for type “F”, 230VAC for type “FL”, or 24VDC for type “FD” cooling fan. If the resistor module’s temperature exceeds 45C and fan voltage is present, return the unit for repair or replacement.
6.1. ATINGS The following tables list the ratings for all M3575R modules currently available. If a desired module rating is not listed below, please contact the equipment supplier or systems integrator for availability information. Please note that the resistance values listed in Tables 6-1 through 6-4 have a tolerance of 10%.
