Notes And Warnings
Please observe the following when handling, connecting and using
your IB462He Driver and INT-462 Interface Board. Failure to
observe these points may result in damage to the drive. All
warranty and disclaimer information is located in the full product
manual and should be referenced for more information.

Power Interface
Motor Supply
Pins 13&14 (+V) and Pins 15&16 (Ground) are used to connect
the DC motor power to the IB462He Driver. Two local capacitors
must be connected to Pins 13&14 and Pins 15&16. These
capacitors must be located as close to the IB462He motor
supply input pins as possible to ensure stable operation.
+5 VDC Input
The IB462He requires an external +5 VDC power supply which is
connected between Pin 5 (+V) and ground. The +5 VDC supply
ground and the motor supply ground must not be connected to
each other at the power supplies. The +5 VDC ground must be
connected to the ground pin of the electrolytic capacitor.
Required Capacitors
The first capacitor is a low impedance, aluminum electrolytic. The
continuous operating voltage of the capacitor must exceed the
maximum supply voltage as well as any back EMF voltage
generated by the motor. The capacitance should be 150 µF for
each amp of peak phase output current.
Example: 1.4A peak @ 40 VDC x 150 µF = 220 µF 60V.
A 0.1 µF 100V capacitor must be used to filter high frequency
noise. It must be placed between the motor power input pins
13&14 (+V) and 15&16 (ground) and the electrolytic capacitor.
The continuous operating voltage of this capacitor must exceed
the maximum supply voltage as well as any back EMF voltage
generated by the motor.
The +5 VDC supply requires a 22 µF 10V Tantalum capacitor to
be installed as close to the IB462He Driver as possible between
Pin 5 (+5V) and ground.
The IB462He and INT-462 components are sensitive to
Electrostatic Discharge (ESD). All handling should be done
at an ESD protected workstation.
Hazardous Voltage Levels may be present if using an open
frame power supply to power the IB462He and INT-462.
The Power Supply output voltage must not exceed the
maximum input voltage of the IB462He and INT-462.
Do not apply power to the IB462He without proper heatsinking
or cooling. The maximum rear plate temperature of the
IB462He is 70°C!
The rear mounting surface of the driver contains various
voltages and must be kept isolated when attached to a
conductive surface!
Do not connect or disconnect power leads or motor leads when
power is applied! Disconnect the AC power side to power down
the DC power supply.
For battery operated systems, conditioning measures should
be taken to prevent device damage caused by in-rush current
draws, transient arcs and high voltage spikes.
