The power supply checks the system status:
If the status is correct:
The
System OK
contact closes (pins 6 and 7 of X6) and it stays
closed while the control circuits are powered and no error comes up in
any of the modules of the system.
The red <FAULT> indicator light blinks (it is not indicating an error be-
cause there are no phases yet).
If the status is not correct:
The red <FAULT> indicator light is permanently on (not blinking).
3.
Apply power to the main power supply:
Power is applied from mains through the power connector
(1) on top of
the power supply (L1, L2, L3). The red <FAULT> indicator light will turn
off and the smooth start-up will begin.
4.
The green DC BUS ON light on:
Having mains voltage and being the PWM Enable signal (pin 4 of con-
nector X6) active, after 4 seconds, the green DC BUS ON indicator
light turns on meaning that the power bus has the proper dc voltage.
If for any reason an error is activated at the power supply module or at
any drive module it supplies to, the system will act as follows:
1.
The green indicator light DC BUS ON will turn off indicating that the
power supply will stop supplying voltage to the power bus.
2.
The red FAULT light will be on permanently.
With the Error Reset input (pin 1 of X6), it is possible to eliminate the er-
rors at the drives that are part of the system
- see chapter 14, section “re-
settable errors”, of the “man_dds_soft.pdf” manual - and it acts as follows:
Its state will be 0 V DC. Activating it with 24 V DC erases all the errors
stored in the memory of each drive of the system.
Should the cause of the error persist, the corresponding module will
show the same error again and it will be necessary to turn the unit
back on to eliminate the error if it is a serious error.
The System Speed Enable input (pin 5 of X6) is related to the Speed En-
able inputs of the drive modules.
The state of the System Speed Enable is usually 24 V DC.
If the System Speed Enable pin is set to 0 V DC, all the drive modules
joined together by the same internal bus will brake the motors that they
control with the torque corresponding to the active acceleration ramp
and when stopped or when reaching the time limit to stop (programma-
ble with parameter GP3, see chapter
13 of the “man_dds_soft.pdf”
manual), it cancels the motor torque.
The consumption of each input is between 4.5 and 7 mA.
NOTE.
If the PWM Enable (pin 4 of connector X6) is not active, the
display will show the warning A004 and the power bus of the RPS will
not start charging.
DANGER.
When the DC BUS ON led turns off it may take about 4 min-
utes for the bus to discharge to a safe value (< 42 V DC) depending on
the number of drive modules that are connected.
NOTE.
Remember that
if the RPS power supply is running, there is
mains voltage and the PWM Enable signal is active. When canceling the
PWM Enable signal the display shows the warning A004, turns on the
FAULT LED and the power supply stops boosting the voltage causing a
voltage drop with a value of
2 x Vred at the power bus. The drives con-
nected to the power supply will interpret that the power supply is not ok.
