3.1 Electrical Noise Immunity

Location for Use

This device corresponds to Class A according to EN 55022 and is intended primarily for operation in industrially zoned areas.

Remember that the vulnerability of electronic equipment to noise increases with faster signal processing and higher sensitivity. Protect your equipment by observing the following rules and recommendations.

Noise voltages are mainly produced and transmitted by capacitive and inductive coupling. Electrical noise can be picked up by the inputs and outputs to the equipment, and the cabling.

Likely sources of interference are:

Strong magnetic fields from transformers and electric motors

Relays, contactors and solenoid valves

High-frequency equipment, pulse equipment and stray magnetic fields from switch-mode power supplies

Mains leads and leads to the above equipment

Electrical interference can be avoided by:

A minimum distance of 20 cm between the logic unit (and its leads) and interfering equipment.

A minimum distance of 10 cm between the logic unit (and its leads) and cables carrying interference signals. (Where signal cables and cables that carry interference signals are laid together in metallic ducting, adequate decoupling can be achieved by using a grounded separation shield.)

Shielding according to IEC 742 EN 50 178

Potential compensating lines — 6 mm²/10 mm² (see Grounding Plan)

Use of original HEIDENHAIN cables, connectors and couplings.

3.2 Heat Generation and Cooling

Please note that the reliability of electronic equipment is greatly reduced by continuous operation at high temperatures. Be sure to make the necessary arrangements to keep within the permissible ambient temperature range.

Permissible ambient temperature in operation: 0 °C to 45 °C (32 to 113 °F)

The following means may be employed to ensure adequate heat removal:

Provide sufficient space for air circulation.

Build in a fan to circulate the air inside the control cabinet. The fan must reinforce the natural convection. It must be mounted so that the warm air is extracted from the logic unit

and no pre-warmed air is blown into the unit. The warmed air should flow over surfaces that have good thermal conductivity to the external surroundings (for example sheet metal).

For a closed steel housing without assisted cooling, the figure for heat conduction is 3 Watt/m² of surface per °C air temperature difference between inside and outside.

Use of a heat exchanger with separate internal and external circulation.

Cool by blowing external air through the control cabinet to replace the internal air. In this case the fan must be mounted so that the warm air is extracted from the control

cabinet and only filtered air can be drawn in. HEIDENHAIN advises against this method of cooling, since the function and reliability of electronic assemblies are adversely affected by contaminated air (fine dust, vapors, etc.). Besides these disadvantages, a filter that is not adequately serviced leads to a loss in cooling efficiency. Regular servicing is therefore vital.

3.3 Humidity

Permissible humidity:	< 75% in continuous operation,
	< 95% for not more than 30 days p.a. (randomly distributed).

In tropical areas it is recommended that the TNC not be switched off, so that condensation is avoided on the circuit boards. The heat generation prevents condensation and has no further disadvantages.

3.4 Mechanical Vibration

Permissible vibration: < 0.5 m/s2

3.5 Degree of Protection

HEIDENHAIN recommends that you operate the PLC of the LE (and the PL 410B/PL 405B) with a 24 V control voltage that is generated as per VDE 0551. The control voltage must be smoothed with approx. 150µF / A (at 15 A, this corresponds to a smoothing capacity of 2250 µF), where a minimum capacity of 1000µF (63V) is to be ensured.

The 0 V line of the PLC power voltage must be connected by a grounding line ( 6 mm2) with the central signal ground of the machine.

Supply	Voltage range,				Max. current consumption	Current
voltage	mean dc voltage				(when half of the outputs	consumption
					are on simultaneously)	(when half of the
						outputs are on

	19,2 V - - -,

VDE 0411 Part

Besides the voltage tolerance, a dc component with a peak value of 5% of the rated voltage is permissible. The absolute limits lie at 30 V/19.2 V.

Danger to internal components!

Use only original replacement fuses.

3.7.3 Measuring System Inputs

HEIDENHAIN TNC contouring controls are designed for use with incremental linear and angular encoders as measuring systems.

However, HEIDENHAIN recommends using encoders with distance-coded reference marks because they significantly reduce the traverse distance required to establish the absolute position.

Maximum current load per encoder input:

200 mA

Use only original HEIDENHAIN encoder cables, connectors and couplings. For maximum cable lengths see “Cable Overview.”

Encoder for Position with 1 VSS

Maximum input frequency: 350 kHz (via MP 115.1 switchable to 50 kHz)

3.7.4 Reference Signal for the Spindle

Usually, the reference mark of the spindle encoder is evaluated as a reference signal for the spindle. In special cases, a 24 V signal on terminal X30 can be evaluated as a reference signal for the spindle or as a reference signal release (see chapter “Spindle”). For reliable evaluation, the signal must last for at least 3 milliseconds.

The connecting cables to the nominal value outputs must not have more than one intermediate terminal.

If it is necessary to branch to physically separate servo inputs, the connection must be made in a grounded terminal box. Suitable terminal boxes are available from HEIDENHAIN (Id. Nr. 251 249 01).

The chassis of the terminal box must be electrically connected with frame of the machine.

The 0 V connection of the nominal-value-difference inputs must be connected with signal ground. Required cross section Ø 6 mm².

Use only original HEIDENHAIN connecting cables and connecting elements.

3.7.8 Switching Outputs 24 Vdc for the PLC

Transistor outputs with current limiting

	Logic unit	PL 410 B/PL 405 B
Min. output voltage for “1” signal	3 V below supply voltage
Nominal operating current per output	0.125 A with simultaneity	1.2 A with simultaneity
	factor of 0.5	factor of 0.5;
		2 A with max. current
		consumption of 20 A

Permissible load: resistive load; inductive load only with quenching diode parallel to the inductance.

No more than one output may be shorted on the logic unit at any time. Short circuit of one output does not cause an overload.

No more than half the PLC outputs may be driven at the same time (simultaneity factor 0.5).
