2.2 Motherboard Electrical Description
When power is applied to the PMI Regulator, the PMI processor will perform a series
of internal diagnostics. If the diagnostics are passed, the OK LED will turn on and
remain on.
The PMI processor will request its operating system from the UDC module as soon as
communications are established over the fiber-optic link. After the operating system
has been downloaded from the UDC module (a process that takes approximately 1/2
second), diagnostics are performed on the AC power technology circuit.
RPI (green) - When lit, this LED indicates that the run permissive input
(RPI) signal is detected on pin A. The RPI signal typically
originates from the drive’s coast-to-rest stop circuit.
Corresponding bit location: Register 201/1201, bit 0.
MCR (amber) - When lit, this LED indicates the MCR (motor control relay)
output signal is being driven on (pin P). The MCR output is
under the control of the PMI Regulator.
AUX IN1 (green) - When lit, this LED indicates the presence of a 115 volt signal
on this input (pin C).
Corresponding bit location: Register 201/1201, bit 1.
AUX IN2 (green) - When lit, this LED indicates the presence of a 115 volt signal
on this input (pin E).
Corresponding bit location: Register 201/1201, bit 2.
AUX IN3 (green) - When lit, this LED indicates the presence of a 115 volt signal
on this input (pin H).
Corresponding bit location: Register 201/1201, bit 3.
AUX IN4 (green) - When lit, this LED indicates the presence of a 115 volt signal
on this input (pin K).
Corresponding bit location: Register 201/1201, bit 4.
AUX IN5 (green) - When lit, this LED indicates the presence of a 115 volt signal
on this input (pin M).
Corresponding bit location: Register 201/1201, bit 5.
AUX OUT (amber) - When lit, this LED indicates the output signal has been turned
on (pin S).
Corresponding bit location: Register 101/1101, bit 4.
