Installation Precautions –
IMPORTANT, PLEASE READ BEFORE INSTALLATION
Precaution
Action
Reason
Power supply
If the power supply is not sized
appropriately for the number of
cards/rollers it provides power to, then
a low voltage condition may occur.
•
If the voltage drops below 15V DC and
remains low for 1s, then the low voltage
error will appear
•
If the voltage drops below 15V DC five
times in 0.5s, then the low voltage error
will appear
•
If the voltage drops below 15V DC less
than five times in 0.5s or does not
remain low for 1s, the roller may stutter
– quickly turning off then on
Multiple power
supplies
0V line of the power supply for the
card must be common to the 0V line of
the power supply for the controls
(RUN, DIR, etc.).
This completes the signal path from the
controller (PLC, etc.) to the motor driver card.
Voltage drop
across the
power bus
Use suitable gauge wire in relation to
distance and current draw to prevent
voltage drop.
Operating DC voltage is 24V ±10%
When running long distances from a DC
power supply, the voltage drop during motor
operation across the power bus may be
significant (may drop below 15V!). If there is
a large enough drop in voltage, the roller(s)
may behave in a strange manner. In order to
prevent this, a larger gauge wire must be
used.
Grounding
Ensure the control card is securely
grounded to the conveyor frame. The
conveyor frame should also be at the
same potential reference as earth
ground. Standard grounding practices
should be followed.
Static discharge may interfere and damage
internal components.
Electrical
24V DC ±10%
4A maximum current limiter
(motor lock is 4A)
Diode protection for mis-wiring
Sensor power short circuit protection
5A fuse for power supply protection
Auto-sensing inputs for PNP or NPN
Improper power will damage the card.
The motor/card should not be subject to
locked conditions repeatedly.
Internal fuse is not replaceable. If the fuse
has blown, more serious damage has
occurred within the card/motor.
If inputs are subjected to a low potential the
card may see this as a signal, use of a diode
inline is recommended to prevent this.
Environment
Ambient temperature is 32~104°F
Ambient humidity is < 90%RH
Atmosphere has no corrosive gas
Vibration is < 0.5G
Indoor use only
Extreme environmental variables may
cause poor or no performance and
damage the card.
