1. INTRODUCTION

1.1 Operation principle of BCU

When you want to slow down a running asynchronous motor fed by a frequency converter it turns
into a generator, feeding energy back into the frequency converter. The energy increases the voltage
in the DC-link. The frequency converter compensates for this increase by increasing the output
frequency, decreasing the instantaneous slip and increasing the motor load. The deceleration is, in
this case, dependent on the power losses in the converter and in the motor. This is usually sufficient
in most cases, for pumps, fans, conveyors etc. where the kinetic energy in the load is small or the
braking time is not critical.

When you have to brake down the motor faster than the losses allow, you have to use BCU module
and an external brake resistor (or resistors) for energy dissipation. The extra energy from the load
is turned into heat in the brake resistor. If the DC link voltage increases too much, the BCU turns on
and discharges the capacitors through the brake resistor. Applications where dynamic braking is
usually needed include centrifuges, cranes, some conveyors and drives requiring very fast
reversing.

Modules can be connected parallel with other BCU modules in order to increase braking capacity
(Figure 1).

In BCU application you can use either Analogue input or OPT-B8 option board for PT100 sensor
connection.

Start-up sequence of BCU application has been illustrated in Figure 2.

1.2 Quick start instructions

NOTE! Before taking any commissioning actions read carefully the safety instructions in Vacon NX

User's Manual, chapter 1.

1. Check installations (see Figure 3, Table 2-1 and Table 2-2).

2. Check resistor(s) max. temperature durability.

3. Switch power on.

4. Set PT-100 parameters (P2.2.2.1, P2.2.2.2 and P2.6.1 – P2.6.3) or KLIXON input settings
(P2.2.1.4).

5. Set brake chopper operation level to preferred value (P2.1.2).

6. In case of parallel BCU set Drooping (P2.4.1) = 5%.

7. Set Digital input parameters (P2.2.1.1 – P2.2.1.4) according to connections.

8. Test BCU.

9. If fault occurs see chapter 6.

Brake chopper operation level in volts. This is the DC link voltage level when the BCU
starts to discharge the capacitors through the brake resistor.

2.1.2 ID Run (ID631)

This parameter is used for manual identification for brake resistor connection. Brake
chopper unit makes automatic identification during every power-up. However, if resistor
connection is changed during service, ID Run can be executed manually with this

This parameter defines if the BCU monitors status of the External fault input. With
External fault it is possible to trig a fault 51. Response to the fault can be defined with
the parameter P2.6.5.

See parameter P2.2.1.1 for the list of values.

2.2.1.3 Run Enable (ID1212)

This parameter is used for choosing the input for external Run Enable signal. If the
option “0 = Not used” have been selected the Run Enable signal is always on.

See parameter P2.2.1.1 for the list of values.

2.2.1.4 KLIXON Input (ID1209)

This parameter is used for choosing the input for KLIXON type temperature sensor. The
function of this input is Normally Closed so the fault “60 = KLIXON” is generated when
the input goes low.

Note: If the selected value is greater than the actual number of used PT100 inputs, the
display will read 200ºC. If the input is short-circuited the displayed value is –30ºC.

This parameter is visible only when there is OPTB8 option board installed in the
BCU.

2.6.2 PT100 Alarm limit (ID1347)

Set here the limit at which the PT100 alarm will be activated.

2.6.3 PT100 Fault limit (ID1348)

Set here the limit at which the PT100 fault will be activated.

2.6.4 Response to thermistor fault (ID1351)

0 = No response
1 = Warning
2 = Fault

Setting the parameter to 0 will deactivate the protection.

2.6.5 Response to External fault (ID1351)

0 = No response
1 = Warning
2 = Fault

This parameter defines a response to an external fault. If the BCU monitors state of the
external fault input (value of P2.2.1.2 > 0) and a fault occurs the drive can be set to
respond to the fault.

4.7 Keypad control

3.1 Control place (ID125)

The active control place can be changed with this parameter.

0 = I/O terminal (default)
1 = Fieldbus

6. FAULT CODES

The fault codes, their causes and correcting actions are presented in the table below. The shadowed
faults are A faults only. The items written in white on black background present faults for which you
can program different responses in the application. See parameter group Protections.

Note: When contacting distributor or factory because of a fault condition, always write down all texts
and codes on the keypad display.
