18.3.2. POWER SUPPLY FOR
SIGNALS
(1)
Internal Power Supply
Internal power supply
for
signals should be provided by the machine tool maker. If
internal power supply is used, calculate the load current according to
points and confirm
that the current is within the allowable current value since there is a current capacity limit
according to
ON points.
The allowable current capacity of the internal power supply is 1. 5A.
Unit consumed current (When internal power supply is used): O. 1A
Panel
consumed current (When internal power is used)
Remote
Input current (l-point): 5.
(at ON)
Output current (1 -point):
max (differs from load,
module
consumed current
Input current (1 -point): 10.
(at ON)
Output current (1 -point):
max (differs from load.
(Example of Calculation)
When JANCD-FC903 All
output are ON with LED load (2.
5.1 mAX64=326.
comsumed current)
24V/2. 7kX32=28.
output comsumed current)
1500mA–326mA–284 mA–100mA=790mA (possible supply current)
If the internal power supply is connected to JANCD-FC800 under these conditions, overcurrent
alarm of the internal power supply (C
or
occurs to the input ON of 77 points or
above.
O. 2mA=77 points
(2) Specifications of External Power Supply
Voltage 24VDC
Ripple 10% (P-P)
Provide external supply with the above.
