Manual Slider SFX
2.1 Base settings on delivery
The board is shipped in a base setting, were all jumper are set to position 1-2, JP10 and
JP11 are open, JP12 is closed. This results in the following functional assignment on the
interface X10 (input from the parallel port of a PC):
Pin 14
switches relay 2
Pin 15
is general input
Pin 16
switches relay 3
Pin 17
controls the current reduction of the motors (low active)
For a complete description of the interface X10 please refer to section 2.5.
The voltage range on the analogue output (to control a main spindle) is set to 0-10V. The
monitoring of the toggle signal is disabled. Relays are not inverted and the start up time is
aprox. 3 seconds.
The DIP switches are set in a way that all motors are driven with 1.0A and in quarter step
mode, meaning with 800 steps/rev for a standard 1.8° motor.
2.2 Mounting and ventilation
Slider SFX
is tested for ambient temperatures of up to 50°C. An
HT
version is available
for ambient temperatures of up to 70°C. When mounting the board into a case, sufficient
ventilation has to be provided, e.g. by placing adequate ventilation slots in the case hood.
The fan that is mounted on the side of the
Slider SFX
board can be used on both sides of
the board, according to assembly and ventilation in the case. If a case with integrated fan
is used, the air stream should pass the 6 drivers (IC’s 1, 2, 5, 7, 12 and 17). The direction of
the board’s fan air stream should be adjusted in the same direction as the case fan. If the
ventilation of the case is sufficient, the fan on the board might be redundant.
Warning:
Ventilations slots (for active or passive cooling) should be covered with filter pads
of at least 30 ppi to protect them against intrusion of chips. Intruding chips and
metal parts can influence the function of the board and may also completely dest-
roy it!
The
HT
version for ambient temperatures up to 70°C is equipped with a 10mm thick alu-
minium heat sink on the bottom side. This heat sink has to be mounted to the bottom
plate of the case with its full surface. This ensures optimal heat conduction.
