Notes:
- "O"
designates an output from the drive.
- "I"
designates an input to the drive.
- "I/O"
designates an input/output common.
- "PWR"
designates a power supply to the drive.
- Reserved
designates reserved pins which must be left unconnected.
- Pins 47, 48, 49,
and 50 are the address selection pins. See jumper
settings for address information.
|
+5 volt power supply |
There are two input pins
for +5 Volt power supply, "+5V Logic" and "+5V
Motor." "+5V Logic" is connected to the internal
logic circuits and "+5V Motor" is connected to the spindle
motor and motor drive. |
It is possible to turn
on and off "+5V Logic" by an external switch circuit to
reduce power consumption to the least possible. In this mode, a
voltage drop out due to the motor spin up current can be reduced by
connecting "+5V Motor" line into the system power source
directly. |
