4.5.1 Supply requirements
Maximum supply in-balance: 2% negative phase sequence (equivalent
to 3% voltage in-balance between phases)
Frequency range: 48 to 65 Hz (maximum rate of frequency change is 7
Hz/s)
4.6 Separating the Auxiliary Supply
The Quantum MP drive is delivered from the factory with the auxiliary
supply terminals E1 and E3 are pre-wired to the drive AC power
terminals L1 and L3. This is adequate for most installations. If it is
necessary to power the auxiliary supply from a separate source, the
following steps must be taken:
1.
Ensure that the main AC supply and any other hazardous energy
sources are turned off and locked out before attempting to remove
the Quantum drive cover or auxiliary wiring.
2.
Wait for 10 minutes after turning off the electrical supply for any
stored electrical energy to dissipate.
3.
Remove the Quantum MP cover (size 1only).
4.
Locate and completely remove from the drive the two 10 AWG wires
that run from L1 to E1 and L3 to E3.
5.
Connect the separate auxiliary supply to the Quantum MP, E1 and
E3 terminals using a 10 A 600 V branch circuit rated fuse in each
line. Note: The separate auxiliary supply must be in phase with the
main supply lines L1 and L3.
6.
Reconfigure the 120 Vac control transformer per Table 4-6 for the
auxiliary supply voltage.
7.
Replace the Quantum MP cover (size 1 only).
4.7 Control 120 Vac supply
The on board 120 Vac power source (size 1 or panel mounted size 2,
terminals X1 Line and X2 Neutral) for the 120 Vac digital I/O is derived
from an internal control transformer. This transformer is powered from
terminals E1 and E3 which are pre-wired to line input terminals L1 and
L3. The transformer is pre-wired at the factory for 480 Vac line input. If
the drive system will be powered from a source other than 480 Vac, the
leads on the MP18 (size 1) or T1 transformer primary terminal (size 2)
board need to be configured as outlined in Table 4-6
or Table 4-7
Transformer connections, Size 2
.
Table 4-6 Transformer connections, Size 1
The 120 Vac digital I/O power source at terminals X1 and X2 is
protected by a 1/2 Amp FNQ-R type fuse on the primary side. This
source is also used internally to power the contactor control circuitry.
Total load current on the 120 Vac output at terminals X1 and X2 must
not exceed 250 mA.
Table 4-7 Transformer connections, Size 2
The 120 Vac digital I/O power source at terminals X1 and X2 is
protected by 2 -1 Amp FNQ-R type fuses on the primary side. This
source is also used to power the contactor. Total load current on the 120
Vac output at terminals X1 and X2 must not exceed 1.25 Amp.
4.8 Control 24 Vdc supply
The 24 Vdc input has three main functions.
•
It can be used to supplement the drive's own internal 24 Vdc when
multiple SM-Universal Encoder Plus, SM-Encoder Output Plus, SM-
I/O Plus, or SM-I/O 32 modules are being used and the current
drawn by these modules is greater than the drive can supply. (If too
much current is drawn from the drive, the drive will initiate a 'PS.24V'
trip)
•
It can be used as a back-up power supply to keep the control circuits
of the drive powered up when the line power supply is removed. This
allows any fieldbus modules, application modules, encoders or serial
communications to continue to operate.
•
It can be used to commission the drive when the line power supply is
not available, as the display operates correctly. However, the drive
will be in the UV trip state unless the line power supply is enabled,
therefore diagnostics may not be possible. (Power down save
parameters are not saved when using the 24V back-up power
supply input.)
The working voltage range of the 24 V power supply is as follows:
Maximum continuous operating voltage:
30.0 V
Minimum continuous operating voltage:
19.2 V
Nominal operating voltage:
24.0 V
Minimum start up voltage:
21.6 V
Maximum power supply requirement at 24 V:
60 W
Recommended fuse:
3 A, 50 Vdc
Minimum and maximum voltage values include ripple and noise. Ripple
and noise values must not exceed 5%.

Verify 120 Vac control transformer is configured per Table 4-
6 or Table 4-7. Before applying line voltage to drive system!
Otherwise, damage to control transformer and/or 120 Vac I/
O protection fuse F3 (size 1 only) could result.
