2	Safety instructions
	General safety and application notes for Lenze controllers

Application as directed

Controllers are components which are designed for installation in electrical systems or machines. They are not to be used as domestic appliances, but only for industrial purposes according to EN 61000−3−2.

When controllers are installed into machines, commissioning (i.e. starting of the operation as directed) is prohibited until it is proven that the machine complies with the regulations of the EC Directive 2006/42/EC (Machinery Directive); EN 60204 must be observed.

Commissioning (i.e. starting of the operation as directed) is only allowed when there is compliance with the EMC Directive (2004/108/EC).

The controllers meet the requirements of the Low−Voltage Directive 2006/95/EC. The harmonised standard EN 61800−5−1 applies to the controllers.

The technical data and supply conditions can be obtained from the nameplate and the documentation. They must be strictly observed.

Warning: Controllers are products which can be installed in drive systems of category C2 according to EN 61800−3. These products can cause radio interferences in residential areas. In this case, special measures can be necessary.

Transport, storage

Please observe the notes on transport, storage, and appropriate handling.

Observe the climatic conditions according to the technical data.

Installation

The controllers must be installed and cooled according to the instructions given in the corresponding documentation.

The ambient air must not exceed degree of pollution 2 according to EN 61800−5−1.

Ensure proper handling and avoid excessive mechanical stress. Do not bend any components and do not change any insulation distances during transport or handling. Do not touch any electronic components and contacts.

Controllers contain electrostatic sensitive devices which can easily be damaged by inappropriate handling. Do not damage or destroy any electrical components since this might endanger your health!

General safety and application notes for Lenze controllers

Electrical connection

When working on live controllers, observe the applicable national regulations for the prevention of accidents (e.g. VBG 4).

The electrical installation must be carried out according to the appropriate regulations (e.g. cable cross−sections, fuses, PE connection). Additional information can be obtained from the documentation.

This documentation contains information on installation in compliance with EMC (shielding, earthing, filter, and cables). These notes must also be observed for CE−marked controllers. The manufacturer of the system is responsible for compliance with the limit values demanded by EMC legislation. The controllers must be installed in housings (e.g. control cabinets) to meet the limit values for radio interferences valid at the site of installation. The housings must enable an EMC−compliant installation. Observe in particular that e.g. the control cabinet doors have a circumferential metal connection to the housing. Reduce housing openings and cutouts to a minimum.

Lenze controllers may cause a DC current in the PE conductor. If a residual current device (RCD) is used for protection against direct or indirect contact for a controller with three−phase supply, only a residual current device (RCD) of type B is permissible on the supply side of the controller. If the controller has a single−phase supply, a residual current device (RCD) of type A is also permissible. Apart from using a residual current device (RCD), other protective measures can be taken as well, e.g. electrical isolation by double or reinforced insulation or isolation from the supply system by means of a transformer.

Operation

If necessary, systems including controllers must be equipped with additional monitoring and protection devices according to the valid safety regulations (e.g. law on technical equipment, regulations for the prevention of accidents). The controllers can be adapted to your application. Please observe the corresponding information given in the documentation.

After the controller has been disconnected from the supply voltage, all live components and power terminals must not be touched immediately because capacitors can still be charged. Please observe the corresponding stickers on the controller.

All protection covers and doors must be shut during operation.

Safety functions

Certain controller versions support safety functions (e.g. "Safe torque off", formerly "Safe standstill") according to the requirements of the EC Directive 2006/42/EC (Machinery Directive). The notes on the integrated safety system provided in this documentation must be observed.

Maintenance and servicing

The controllers do not require any maintenance if the prescribed operating conditions are observed.

Disposal

Recycle metal and plastic materials. Ensure professional disposal of assembled PCBs.

The product−specific safety and application notes given in these instructions must be observed!

	Thermal motor monitoring

2.2Thermal motor monitoring

) Note!

From software version 8.1 onwards, the 9300 vector controllers are provided with an I2xt function for sensorless thermal monitoring of the connected motor.

ƒI2xt monitoring is based on a mathematical model which calculates a thermal motor utilisation from the detected motor currents.

ƒThe calculated motor utilisation is saved when the mains is switched off.

ƒThe function is UL−certified, i.e. additional protective measures for the motor are not required in UL−approved systems.

ƒNevertheless, I2xt monitoring does not provide full motor protection because other influences on the motor utilisation such as changes in the cooling conditions (e.g. cooling air flow interrupted or too warm) cannot be detected.

Die I2 x t load of the motor is displayed in C0066.

The thermal loading capacity of the motor is expressed by the thermal motor time constant (t, C0128). Find the value in the rated motor data or contact the manufacturer of the motor.

The I2 x t monitoring has been designed such that it will be activated after 179 s in the event of a motor with a thermal motor time constant of 5 minutes (Lenze setting C0128), a motor current of 1.5 x IN and a trigger threshold of 100 %.

Two adjustable trigger thresholds provide for different responses.

ƒAdjustable response OC8 (TRIP, warning, off).

–The trigger threshold is set in C0127.

–The response is set in C0606.

–The response OC8, for instance, can be used for an advance warning.

ƒFixed response OC6−TRIP.

–The trigger threshold is set in C0120.

Behaviour of the I2 x t monitoring	Condition
The I2 x t monitoring is deactivated.	When C0120 = 0 % and C0127 = 0 %, set controller
C0066 is set = 0 % and	inhibit.

The current value in C0066 and at the	enable.
MCTRL−LOAD−I2XT output is frozen.
I2 x t monitoring is deactivated.	Set C0606 = 3 (off) and C0127 > 0 %.
The motor load is displayed in C0066.

) Note!

An error message OC6 or OC8 can only be reset if the I2 x t load falls below the set trigger threshold by 5 %.

Thermal motor monitoring Self−ventilated motors

2.2.2Self−ventilated motors

Due to the construction, self−ventilated standard motors are exposed to an increased heat generation in the lower speed range compared to forced ventilated motors.

JWarnings!

For complying with the UL 508C standard, you have to set the speed−dependent evaluation of the permissible torque via code C0129/x.

Parameter setting

The following codes can be set for I2 x t monitoring:

Code	Meaning	Value range	Lenze setting
C0066	Display of the I2 x t load of the motor	0 ... 250 %	−
C0120	Threshold: Triggering of error "OC6"	0 ... 120 %	0 %

Fig. 2−2 Working point in the range of characteristic lowering

The lowered speed / torque characteristic (Fig. 2−2) reduces the permissible thermal load of self−ventilated standard motors. The characteristic is a line the definition of which requires two points:

ƒPoint 0: Definition with C0129/1

This value also enables an increase of the maximally permissible load.

ƒPoint 1: Definition with C0129/2

With increasing speeds, the maximally permissible load remains unchanged

(IMot = Irated).

In Fig. 2−2, the motor speed and the corresponding permissible motor torque (3) can be read for each working point (2on the characteristic (0) ... 1). 3 can also be calculated using the values in C0129/1and C0129/2 (evaluation coefficient "y", ¶ 15).
