1. BH APPLICATION

The VACON® 20 CP/X drive with +D option contains a preloaded application for instant use.

The parameters of this application are listed in chapter 2.2 of this manual and explained in
more detail in chapter 2.

1.1 Specific functions of Vacon BH application

The Vacon BH application allows flexible use of VACON® 20 CP/X frequency converters.

The visibility of parameters and monitors is arranged in three access levels, selected by pa­rameter P14.1.

Basic:

• Monitor of ASi inputs and outputs (only with +D option and AS-interface connection)

• Monitor of sensors

• Monitor of main motor variables

• Setting of motor data

• Setting of Run control mode and commonly used speed reference

• Setting of basic ramp times

• Setting of quick stop function

• Setting of ASi inputs and outputs functions

Advanced:

• Basic + Monitor of more drive/motor variables

• More options for Start/stop and reference selection

• Setting of a second set of ramp times

• Setting of advanced motor control

• Setting of mechanical brake control

• Setting of protections and autoreset

Service:

• Advanced + Monitor of drive internal I/Os

• Setting of some extra motor control and protections features

• Setting of analogue and relay outputs

1.2 ASi Board Diagnostic

This information is valid only for Vacon® 20X with +D option and AS-interface connection.

Monitor V1.3 shows the state of ASi board, as numeric code.

Visual information is provided by red Fault led on the drive's cover.

Off: no anomaly

On: cumulative fault state. Reset is needed to restore operations.

Slow blinking: ASi board is not powered.

Fast blinking: ASi board is powered, but not communicating (to see V1.3).

A fault condition (code 64) is generated if communication fails while the drive is in Run state in
Automatic mode.

This fault is automatically reset when Manual mode is selected. The drive can operate in Man­ual mode, even though the ASi anomaly is still displayed (alarm code 64).

Run is prevented in Automatic mode, until communications is restored.

2.2.10 Group Protections: Menu PAR G10

Parameters of Motor thermal protection (P10.9 to P10.12 and P10.18-P10.19)

The motor thermal protection is to protect the motor from overheating. The drive is capable of
supplying higher than nominal current to the motor. If the load requires this high current there
is a risk that the motor will be thermally overloaded. This is the case especially at low frequen­cies. At low frequencies the cooling effect of the motor is reduced as well as its capacity. If the
motor is equipped with an external fan the load reduction at low speeds is small.

The motor thermal protection is based on a calculated model and it uses the output current of
the drive to determine the load on the motor.

The motor thermal protection can be adjusted with parameters. The thermal current I

T

speci­fies the load current above which the motor is overloaded. This current limit is a function of the
output frequency.

The thermal stage of the motor can be monitored on the control keypad display. See chapter 1.

Parameters of Stall protection (P10.2 to P10.4)

The motor stall protection protects the motor from short time overload situations such as one
caused by a stalled shaft. The reaction time of the stall protection can be set shorter than that
of motor thermal protection. The stall state is defined with two parameters, P10.3 (

Stall time)

and P10.4 (

Stall frequency limit). If the current is as high as the P1.6 (Current Limit) and the

current limiter has reduced the output frequency below the P10.4 for the time P10.3 than the
set limit the stall state is true. There is actually no real indication of the shaft rotation. Stall
protection is a type of overcurrent protection.

Parameters of Underload protection (P10.5 to P10.8)

The purpose of the motor underload protection is to ensure that there is load on the motor
when the drive is running. If the motor loses its load there might be a problem in the process,
e.g. a broken belt or a dry pump.

Motor underload protection can be adjusted by setting the underload curve with parameters
P10.6 (Underload protection: Field weakening area load) and P10.7 (

Underload protection:

Zero frequency load

), see below. The underload curve is a squared curve set between the zero
frequency and the field weakening point. The protection is not active below 5Hz (the underload
time counter is stopped).

If you use long motor cables (max. 100m) together with small drives (1.5 kW) the
motor current measured by the drive can be much higher than the actual motor
current due to capacitive currents in the motor cable. Consider this when setting up
the motor thermal protection functions.

The calculated model does not protect the motor if the airflow to the motor is
reduced by blocked air intake grill. The model starts from zero if the control board is
powered off.

If you use long motor cables (max. 100m) together with small drives (1.5 kW) the
motor current measured by the drive can be much higher than the actual motor
current due to capacitive currents in the motor cable. Consider this when setting up
the motor thermal protection functions.

The torque values for setting the underload curve are set in percentage which refers to the
nominal torque of the motor. The motor's name plate data, parameter motor nominal current
and the drive's nominal current I

L

are used to find the scaling ratio for the internal torque val­ue. If other than nominal motor is used with the drive, the accuracy of the torque calculation
decreases.

If you use long motor cables (max. 100m) together with small drives (1.5 kW) the
motor current measured by the drive can be much higher than the actual motor
current due to capacitive currents in the motor cable. Consider this when setting up
the motor thermal protection functions.

3. PARAMETER DESCRIPTION

Due to its user-friendliness and simplicity of use, the most parameters only require a basic de­scription which is given in the parameter tables in chapter 2.2.

In this chapter, you will find additional information on certain most advanced parameters.
Should you not find the information you need contact your distributor.

3.1 Motor Settings

P1.1 MOTOR NOMINAL VOLTAGE

Value must be read on motor nameplate. Changing of the value will set the voltage at field
weakening point (P9.2) to value 100%.

P1.2 M

OTOR NOMINAL FREQUENCY

Value must be read on motor nameplate. Changing of the value will set the field weakening
point (P9.1) to same value.

P1.3 M

OTOR NOMINAL SPEED

Value must be read on motor nameplate. Speed must be referred to nominal frequency and
nominal load condition (not synchronous speed).

P1.4 M

OTOR NOMINAL CURRENT

Value must be read on motor nameplate.

P1.5 M

OTOR COS PHI

Value must be read on motor nameplate.

P1.6 C

URRENT LIMIT

Maximum motor current supplied from the drive. This parameter is automatically set equal to
150% of motor nominal current, when P1.4 is modified. If a different limit is wanted, it must be
programmed after setting of P1.4.

P1.7 U/

F CURVE OPTIMIZATION

0: Not used

1: Automatic voltage boost (improves motor torque).

P1.8 M

OTOR CONTROL MODE

0: Frequency control

1: Speed control (sensorless control)

In speed control, the motor slip is compensated.

P1.9 L

OAD DROOPING

This function increases the natural slip of asynchronous motors, by decreasing the output
frequency proportionally to motor torque. Frequency is instead increased if the motor is brak­ing. This can help the load sharing, when motors driven by different converters are mechani­cally coupled.

vacon • 35 Parameter description

3

The parameter sets the speed variation (as % of nominal speed) when the motor is at 100%
load. Normally droop action is decreased when the motor is running at low speed. Parameter
P9.9 allows to set a speed independent droop.

P1.10 M

OTOR IDENTIFICATION

This procedure measures motor stator resistance and automatically sets U/f characteristic, to
obtain good torque also at low speed.

0: not active

1: standstill identification

Run command must be given and hold high within 20s after programming the value 1. The mo­tor does not rotate and the drive will automatically exit run state at the end of the measure­ments.

Procedure sets the following parameters: P9.3, P9.4, P9.5, P9.6, P9.7.

Also speed control (P1.8 =1) is activated.

Note: optimized U/f settings will cause motor current values comparable to nominal one, also
at very low speed. External cooling of the motor is needed if the motor works in this condition
for significant time.

3.2 Start/Stop settings

P2.1 START/DIRECTION LOGIC

AUTO Start/Direction logic

These logics are based on Start1 and Start2 signals (defined with P5.1 and P5.2), which allow
the control of Run and direction in AUTOMATIC mode.

0 DIN1: run forward on signal level

DIN2: run backward on signal level

1 DIN1: run forward on signal rising edge

DIN2: run backward on signal rising edge

2 DIN1: run on signal level

DIN2: reverse on signal level

3 DIN1: run on signal rising edge

DIN2: reverse on signal level

For mode 0 and 1, only one signal can be high, otherwise alarm 55 is shown.

For mode 1 and 3, Run edge is acquired only if the drive is Ready, in Automatic mode and not
in Quick stop state. Run condition is then kept until the signal is high.

P2.2 AUTO R

UN CONTROL

This parameter is enabled when ASi board is not present. It defines the source for Run control.

0 Start1- Start2 signals

1 Non-ASi fieldbus

P2.3 S

TART FUNCTION

0: Ramping

1: Flying start

P2.4 S

TOP FUNCTION

NOTE: this parameter is forced to 1, in case a Quick Stop signal has been configured.

NOTE: fall of Enable signal, when configured, always determines stop by coasting.

Selection

number

Selection name Description

0Coasting

The motor is allowed to stop on its own inertia. The control
by the drive is discontinued and the drive current drops to
zero as soon as the stop command is given.

1Ramp

After the Stop command, the speed of the motor is deceler­ated according to the set deceleration parameters to zero
speed.

vacon • 37 Parameter description

3

P2.5 QUICK STOP MODE

Quick stop is activated through the input signal defined in P5.14 (or P5.15).

Signal low (or high) forces the drive to stop, ramping down with the time defined in P4.9. The
ramp to zero is continued also in case the signal returns high (or low).

This parameter defines the mode Quick stop is managed.

0: Signal level

Quick stop is set when the signal is low (signal defined in P5.14) or high (signal defined in
P5.15).

It is reset when the drive has reached stop condition and the signal is restored to normal level.
How the drive in AUTO mode actually restarts the motor depend on logic set in P2.1.

If P2.1 = 1 or 3, a new rising edge on Start signal is needed.

If P2.1 = 0 or 2, the drive restarts immediately if Start signal is high.

In MANUAL mode it depends on logic set in P2.6.

If P2.6 = 0, the drive restarts immediately if Start command is still activated.

If P2.6 = 1, a new rising edge on Start command is needed.

1: Signal edge

Quick stop is set on falling edge (signal defined in P5.14) or rising edge (signal defined in P5.15)
of the signal.

It is reset when the drive has reached stop condition and the Start signal (Start command on
operator panel in MANUAL) is low, independently from the level of Quick stop signal.

Quick stop condition can be diagnosed through ASi input. It is also signalled by Alarm 63.

P2.6 M

ANUAL START MODE

0: Level

Once the drive is started in Manual mode, it will automatically resume Run condition after a
fault or a power loss (if ASi voltage is kept up).

It will restart also after a Quick Stop, if P2.5 = 0.

1: Edge

Once the drive is started in Manual mode, a new start is prevented after a fault, a power loss
or a Quick Stop. The previous Run command must be canceled by Stop button, to enable a new
start.

P4.2 D

ECELERATION TIME 1

Ramp time, referred to variation from max frequency to zero.

P4.3 R

AMP 1 S SHAPE

When value is greater than zero, acceleration and deceleration ramps have a S shape.

The parameter is the time needed to reach full acc/dec.

When value is greater than zero, acceleration and deceleration ramps have a S shape. The pa­rameter is the time needed to reach full acc/dec.

The start and end of acceleration and deceleration ramps can be smoothed with this parame­ter. Setting value 0 gives a linear ramp shape which causes acceleration and deceleration to
act immediately to the changes in the reference signal.

Setting value 0.1…10 seconds for this parameter produces an S-shaped acceleration/deceler­ation. The acceleration time is determined with parameters P1.3 and P1.4.

The voltage of the motor changes from zero point voltage P9.6 following a squared curve form
from zero to the field weakening point P9.2. The motor runs under-magnetized below the field
weakening point and produces less torque. Squared U/f ratio can be used in applications where
torque demand is proportional to the square of the speed, e.g. in centrifugal fans and pumps.

P10.12 MOTOR THERMAL TIME CONSTANT

Time at nominal current, to reach nominal temperature.

The time constant is the time within which the calculated thermal stage has reached 63% of its
final value. The bigger the frame and/or slower the speed of the motor, the longer the time
constant.

The motor thermal time is specific to the motor design and it varies between different motor
manufacturers. The default value of the parameter varies from size to size.

If the motor's t6-time (t6 is the time in seconds the motor can safely operate at six times the
rated current) is known (given by the motor manufacturer) the time constant parameter can be
set basing on it. As a rule of thumb, the motor thermal time constant in minutes equals to 2*t6.
If the drive is in stop stage the time constant is internally increased to three times the set pa­rameter value. The cooling in stop stage is based on convection and the time constant is in­creased.

P11.1 AUTOMATIC RESET

0: Disabled

The automatic reset function deletes fault state when the fault cause has been eliminated and
the wait time P11.2 has elapsed. Parameter P11.4 determines the maximum number of auto­matic resets that can be effected during the trial time set by parameter P11.3. The time count
starts from the first automatic reset. If the number of faults detected during the trial time ex­ceeds the values of trials, the fault status becomes permanent and a reset command is need­ed.
