The choice of power supply voltage depends on the required speed
performance of the motor and the motor's inductance. The motor's
holding torque and low-speed torque is unaffected by power supply
voltage. Supply voltage affects motor power (speed times torque)
output and power output increases proportionally with supply
voltage. Motor eddy current heating goes up with the square of the
supply voltage so motor heating outraces the motor's mechanical
power output with increasing supply voltage. The maximum practical
power supply voltage is capped by the motor's rated case
temperature.
Avoid ON / OFF switching of the DC connection to the drive.
Hard-wire the drive to the power supply and switch the power supply
AC input ON / OFF instead. Switching the DC to the drive results in
very high inrush currents. This could potentially damage the P5000
drive or the ON/OFF switch
.

Mounting the P5000
2.4.1 Connector
Removal
The P5000 has one 12-position terminal block for input power, motor power, and
command I/O. The terminal mating connector is a 2-piece modular connector. Each
piece can be removed separately by pulling the connector body upwards and off of the
mating header pins on the P5000.
The connectors must initially be removed to
mount the P5000 to a heatsink or chassis
.
2.4.2 Heat Sink Mounting
A finned aluminum heatsink
is required
for operating the drive above 2A at a 25°C
ambient temperature.
Operating the P5000 at current settings above 2 Amps without a
heatsink will result in damage to the P5000 drive.
The case temperature of the P5000 (measured on the bottom plate) should not
exceed 70°C and for best life should be kept to 50°C or less
.
Use heatsink compound
between the P5000 drive and the heatsink. The drive can be mounted in any
orientation. 6-32 screws should be used in the four half-holes on the bottom plate of
the drive to secure it to the heatsink. The P5000 drive should be mounted with
unobstructed space of at least one half inch (0.50”) around all sides of the drive.
2.4.3 Chassis
Mounting
The P5000 drive can only be mounted on the bottom plate of the chassis. The drive
can be mounted in any orientation. 6-32 screws should be used in the four holes on
