If the cable is correct, check the resolver reference
signal. Install the resolver cable at both ends.
Connect an oscilloscope probe to Connector C3, Pin 4
(extend the probe with a short length of wire to reach
inside the connector housing if necessary) and connect
the probe ground to common (Connector C3, Pin 10).
Apply control power (115 VAC). The reference signal
should be between 11.8 and 12.0 V peak-to-peak (4.17
and 4.24 V RMS) at a frequency of about 8 KHZ. If
necessary, adjust the reference amplitude with
potentiometer 219. This potentiometer is located
between Connectors C2 and C3 and can be adjusted
from the front of the unit without disassembly.
If the reference signal is correct and the feedback
circuitry is not working, your BDS5 may be
malfunctioning. Contact the factory.
2.7.11 Checking the AC Line Voltages
SHOCK HAZARD!
Large voltages are present on
the AC Line. Be very careful
when measuring these
voltages.
Open the circuit breaker or remove the fuses in the AC
Line.
Turn on the AC Line. Use an AC voltmeter to check
and record the 1- or 3-phase line-to-line voltage at the
circuit breaker or fuse holders. Turn off the AC Line.
Note the model number of the PSR4/5 and refer to the
Model Number Tables, in Chapter 1, to confirm
correct AC Line voltage.
2.7.12 Checking the DC Bus Voltage
Remove the AC Line. Wait 5 MINUTES for the DC
BUS to discharge.
WAIT 5 MINUTES FOR THE
DC BUS to DISCHARGE!
The DC Bus is connected to
large capacitors inside the
PSR4/5. These capacitors can
store a lot of energy.
Remove the BUS+ and BUS- leads from the PSR4/5
Power Terminal Block. Disconnect Connector C2
from the PSR4/5.
Turn on Control Power to PSR4/5 Connector C1 and
turn on the AC Line to the PSR4/5 Power Terminal
Block (La, Lb, and Lc).
SHOCK HAZARD!
Large voltages are present on
La, Lb, Lc, BUS+ and BUS-.
Be very careful when
measuring these voltages.
Check and record the DC Bus output voltage at BUS+
with respect to BUS- on the PSR4/5 Power Terminal
Block. It should be approximately 325 VDC for
230 VAC line voltage, or 162 VDC for 115 VAC line
voltage.
REMOVE THE AC LINE VOLTAGE. WAIT 5
MINUTES FOR THE DC BUS TO DISCHARGE.
Reconnect the BUS+ and BUS- leads to the Power
Terminal Block on the PSR4/5. Be careful to
reconnect the leads with the correct polarity. Re-
install Connector C2 on the PSR4/5.
OBSERVE POLARITY OF THE
DC BUS!
When interconnecting
Industrial Drives GOLDLINE
Series Products, connect
BUS+ to BUS+ and connect
BUS- to BUS-.
