Understanding the Power Requirements
This section describes the power requirements for Class 6 M-style SmartMotor power,
CPU power, I/O power and Communications power.
Power Requirements
Requirement:
For Class 6 M-style SmartMotors: control power requires nominal 24 VDC (±20%), do not
exceed 32 VDC; motor power requires from 24 VDC to 48 VDC, do not exceed 48 VDC.
CAUTION:
Control power for M-style motors must be nominal 24 VDC
(±20%). They are not rated for 48 volts.
Details:
Large SmartMotors can draw high current. Therefore, heavy gauge wire is required
to connect the large motors.
Voltages below 18 VDC could cause a brownout shutdown of the CPU, or what would appear as
a power-off reset, under sudden load changes.
CAUTION:
If power is reversed on any standard SmartMotors, immediate
damage WILL occur and the SmartMotor will no longer operate.
When relying on torque/speed curves, pay close attention to the voltage on which they are
based.
During hard, fast decelerations, a SmartMotor can pull up supply voltages to the point of dam-
age if a shunt resistor pack is not used. Protective shunts are available from Moog Animatics.
Special care must be taken when near the upper voltage limit or in vertical applications that
can back-drive the SmartMotor. Gravity-influenced applications can turn the SmartMotor into
a generator and back-drive the power supply voltage above the safe limit for the SmartMotor.
Many vertical applications require a shunt to protect the SmartMotor from damage. Protective
shunts are available from Moog Animatics.
CAUTION:
Many vertical applications and applications with hard, fast decel-
erations require shunts to protect the SmartMotor from damage. Note that
shunts should always be placed between the motor input and any disconnect or
E-stop relay to protect the motor when power is off or E-stop relay contacts
are open.
CPU, I/O and Communications Power
CAUTION:
The maximum allowed supply voltage is 32 VDC. Voltages greater
than the maximum value will damage the equipment.
