INTRODUCTION

Multicontrol Application

1.INTRODUCTION

The Multicontrol Application for Vacon NXL uses direct frequency reference from the analogue input 1 as a default. However, a PID controller can be used e.g. in pump and fan applications, which offers versatile internal measuring and adjusting functions.

The direct frequency reference can be used for the control without the PID controller and it can be selected from the analogue inputs, fieldbus, keypad, preset speeds or motor potentiometer. Special parameters for Pump and Fan Control (Group P2.10) can be browsed and edited after changing the value of par 2.9.1 to 2 (Pump and fan control activated).

The PID controller reference can be selected from the analogue inputs, fieldbus, PID keypad reference 1 or by enabling the PID keypad reference 2 via digital input. The PID controller actual value can be selected from the analogue inputs, fieldbus or the actual values of the motor. PID controller can also be used when the frequency converter is controlled via fieldbus or the control keypad.

•Digital inputs DIN2, DIN3, (DIN4) and optional dig. inputs DIE1, DIE2, DIE3 are freely programmable.

•Internal and optional digital/relay and analogue outputs are freely programmable.

•Analogue input 1 can be programmed as current input, voltage input or digital input DIN4.

NOTE! If the analogue input 1 has been programmed as DIN4 with parameter 2.2.6 (AI1 Signal Range), check that the jumper selections (Figure 1- 1) are correct.

Additional functions:

•The PID controller can be used from control places I/O, keypad and fieldbus

•Identification

•Programming wizard

•Sleep function

•Actual value supervision function: fully programmable; off, warning, fault

•Programmable Start/Stop and Reverse signal logic

•Reference scaling

•2 Preset speeds

•Analogue input range selection, signal scaling, inversion and filtering

•Frequency limit supervision

•Programmable start and stop functions

•DC-brake at start and stop

•Prohibit frequency area

•Programmable U/f curve and U/f optimisation

•Adjustable switching frequency

•Autorestart function after fault

•Protections and supervisions (all fully programmable; off, warning, fault):

•	Current input fault	•	Motor thermal, stall and underload
•	External fault	•	protection
•	Output phase		Thermistor
•	Under voltage	•	Fieldbus communication
•	Earth fault	•	Option board

DESCRIPTION OF PARAMETERS

4.DESCRIPTION OF PARAMETERS

4.1BASIC PARAMETERS

2.1.1, 2.1.2 Minimum/maximum frequency

Defines the frequency limits of the frequency converter.

The maximum value for parameters 2.1.1 and 2.1.2 is 320 Hz.

The software will automatically check the values of parameters 2.1.19, 2.1.20, 2.3.13, 2.5.1, 2.5.2 and 2.6.5.

2.1.3, 2.1.4 Acceleration time 1, deceleration time 1

These limits correspond to the time required for the output frequency to accelerate from the zero frequency to the set maximum frequency (par. 2.1.2).

2.1.5Current limit

This parameter determines the maximum motor current from the frequency converter. To avoid motor overload, set this parameter according to the rated current of the motor. The current limit is equal to the rated converter current (IL) by default.

2.1.6Nominal voltage of the motor

Find this value Un on the rating plate of the motor. This parameter sets the voltage at the field weakening point (parameter 2.6.4) to 100% x Unmotor.

2.1.7Nominal frequency of the motor

Find this value fn on the rating plate of the motor. This parameter sets the field weakening point (parameter 2.6.3) to the same value.

2.1.8Nominal speed of the motor

Find this value nn on the rating plate of the motor.

2.1.9Nominal current of the motor

Find this value In on the rating plate of the motor.

2.1.10Motor cos phi

Find this value “cos phi” on the rating plate of the motor.

DESCRIPTION OF PARAMETERS

2.1.11Start function

Ramp:

0The frequency converter starts from 0 Hz and accelerates to maximum frequency within the set acceleration time. (Load inertia or starting friction may cause prolonged acceleration times).

Flying start:

1The frequency converter is able to start into a running motor by applying a small torque to motor and searching for the frequency corresponding to the speed the motor is running at. The searching starts from the maximum frequency towards the actual frequency until the correct value is detected. Thereafter, the output frequency will be increased/decreased to the set reference value according to the set acceleration/deceleration parameters.

Use this mode if the motor is coasting when the start command is given. With the flying start, it is possible to ride through short mains voltage interruptions.

Conditional flying start

2With this mode it is possible to disconnect and connect the motor from the frequency converter even when the Start command is active. On re-connecting the motor, the drive will operate as described in selection 1

2.1.12Stop function

Coasting:

0The motor coasts to a halt without control from the frequency converter after the Stop command.

Ramp:
1	After the Stop command, the speed of the motor is decelerated according to
	the set deceleration parameters.
	If the regenerated energy is high it may be necessary to use an external
	braking resistor for faster deceleration.

DESCRIPTION OF PARAMETERS

2.1.13U/f optimisation

0	Not used
1	Automatic torque boost
	The voltage to the motor changes automatically which makes the
	motor produce sufficient torque to start and run at low
	frequencies. The voltage increase depends on the motor type and
	power. Automatic torque boost can be used in applications where
	starting torque due to starting friction is high, e.g. in conveyors.
NOTE!	In high torque – low speed applications – it is likely that the motor
	will overheat. If the motor has to run a prolonged time under these
	conditions, special attention must be paid to cooling the motor. Use

external cooling for the motor if the temperature tends to rise too high.

2.1.14I/O Reference selection

Defines the selected frequency reference source when the drive is controlled from the I/O terminal.

0 AI1 reference (terminals 2 and 3, e.g. potentiometer)

1 AI2 reference (terminals 5 and 6, e.g. transducer)

2 Keypad reference (parameter 3.2)

3 Reference from Fieldbus (FBSpeedReference)

4 Motor potentiometer reference

5 AI1/AI2 selection. Selection of AI2 is made programmable by DIN3 Function (P2.1.18)

2.1.15AI2 (Iin) signal range

1 Signal range 0…20 mA

2 Signal range 4…20 mA

3 Signal range 0...10V

4 Signal range 2...10V

Note! The selections have no effect if par. 2.2.12 > 0%, or par. 2.2.13 < 100%.

2.1.16Analogue output function

This parameter selects the desired function for the analogue output signal. See the table on page 5 for the parameter values.
