LED INDICATORS
CURRENT CONTROLLER BOARD 141-108
PWR Power Turns ON GREEN as soon as power is applied to the drive.
Turns OFF when power is removed from the drive.
BUS Bus Status Turns ON RED as soon as power is applied to the drive
Changes to GREEN when voltage across charging resistor drops below 35VDC.
Changes back to RED if there is an OV/UV fault AND the drive is not enabled.
Changes back to GREEN when OV/UV fault is cleared.
Turns off when power is revoved from the drive.
HS1 Hall Sensor 1 Turns on RED when SOUTH magnetic pole is over HS1 in encoder.
Turns off when NORTH magnetic pole is over HS1 in encoder.
HS2 Hall Sensor 2 Turns on RED when SOUTH magnetic pole is over HS2 in encoder.
Turns off when NORTH magnetic pole is over HS2 in encoder.
HS3 Hall Sensor 3 Turns on RED when SOUTH magnetic pole is over HS3 in encoder.
Turns off when NORTH magnetic pole is over HS3 in encoder.
TAC Hall Sensor 4 Turns on GREEN when SOUTH magnetic pole is over HS4 in encoder.
Hall Sensor 5 Turns off RED when SOUTH magnetic pole is over HS5 in encoder.
Turns on BOTH when SOUTH magnetic pole is over both HS4 and HS5.
Turns off when NORTH magnetic poles are over both HS4 and HS5.
ENBL Enable Turns ON YELLOW when:
1.
Drive is in RUN mode with no faults.
2.
Drive is in JOG mode with no faults.
3.
During RAMP STOP with no faults.
Turns off when:
1.
The UnderVoltage Timer times out.
2.
There is an Undervoltage (UV) fault.
3.
There is an OverVoltage (OV) fault.
4.
There is an IOC fault.
5.
There is a STALL fault.
6.
RUN, JOG, and RAMP STOP modes are all off.
STALL Stall Fault Turns ON RED if motor does not move 30° within specified time.
Time is inversely proportional to motor current.
Times out in 1.6 seconds at Current Limit (150% of full load).
Will not time out if current is less than 40% of full load.
Turns off when trips are reset.
PL Power Loss Turns ON RED if the +24 VDC raw supply drops below 18VDC.
Turns ON RED if the +15VDC supply rises to within 3VDC of +24VDC.
Turns off when trips are reset if the condition no longer exists.
OV/UV Overvoltage Turns ON RED in the following cases:
UnderVoltage 1. Bus Voltage is greater than 120% of nominal at any time.
2.
Bus Voltage is less than 75% of nominal at any time.
3.
Bus Voltage is below 85% of nominal for 80 mS or more.
4.
The charging contactor is not energized.
Turns off when trips are reset if the condition no longer exists.
IOC Instantaneous Turns ON RED if bus current to output transistors exceeds 300%.
OverCurrent Turns off when trips are reset.
PHAD Phase Advance Indicates electronic shifting of encoder signals to achieve Constant Horsepower.
GREEN indicates no phase advance.
ORANGE indicates 18° of phase advance timing.
RED indicates 30° of phase advance timing.
SPEED CONTROLLER BOARD 141-107
RUN RUN mode Turns ON GREEN when +24VDC is applied to TB2 terminal 4.
Stays ON GREEN as long as +24VDC is applied to TB2-4 or TB2-5.
Turns off when + 24VDC is removed from BOTH TB2-4 and TB2-5.
CURRENT LIMIT Current Limit Turns on RED when speed demand cannot be satisfied.
One cause is current limit, which is adjustable from 0% to 150% of full load motor current.
Another cause is when the speed required is too great at that load and bus voltage.
Turns off when above conditions cease to exist.
ZERO SPEED Zero Speed Turns ON YELLOW when motor speed exceeds approximately 10 RPM with 120 PPR encoder.
Turns OFF when RUN, JOG or RAMP STOP mode ends.
