Datasheet

The Warn indicator (yellow LED) is lit whenever the motor is more than 128 counts off of the commanded position. Its purpose
is to give warning that a large following error is probably developing and will result in the drive going into FAULT (red LED) if
measures are not taken to arrest the increasing following error.
The Power indicator (green LED) is lit whenever there is power applied to the G320X.
ERROR / RESET PIN
This terminal functions as an ERROR output and as a RESET input. Because this terminal functions as both an input and an
output, some detailed description is necessary.
When first testing the G320X, ERR/RES (Terminal 5) was connected to ENC+ (term. 7). It can be left that way if it is not
necessary to read the state of the ERROR output. Otherwise, the following details are important.
The ERROR output is latched in the “ERROR” state (Terminal 5 = “0”) by the power-on reset circuitry in the G320X. It will stay in
this state indefinitely until it is cleared by applying +5V to this terminal for at least 1 second.
The voltage on this terminal is +5VDC when the G320X is functioning normally. The voltage on this terminal goes to 0VDC
whenever the FAULT indicator is lit. This output can be used to signal your controller that an error has occurred.
Normally when the G320X is first powered up, it will be necessary to push the momentary switch to START for 1 second. This
will clear the power-on reset condition and extinguish the FAULT LED. The motor will then be enabled and the drive will begin
to operate. If at any time after that a condition occurs that causes the G320X to “FAULT out”, such as not being able to
complete a step command, the ERR/RES terminal will go to “0”, signaling to the controller an error has occurred. This will
require the operator to correct the problem that caused the FAULT and then push the switch to “START” for 1 second to re-
enable the G320X.
At any time the operator can push the switch to the “STOP” position to immediately halt the G320X drive. Anytime the G320X is
in the “FAULT” state (FAULT LED lit), all switching action stops, the motor freewheels and is unpowered.
