Operating instructions for electronic handwheel HKA/HKC Safety precautions EUCHNER handwheels HKA/HKC meet the EMC protection requirements according to EN 61000-6-2 and EN 61000-6-4. HKA/HKC handwheel must not be used for residential applications, in business or commercial areas or in small business. The operator of the overall higher-level system is responsible for conformity with the national and international safety and accident prevention regulations applicable to the special application. When designing machines and using handwheels, the national and international safety and accident prevention regulations specific to the application must be observed, e.g.: EN 60204, electrical equipment of machines EN 12100, safety of machines, general design principles EN 13849, safety-related parts of control systems Appropriate safety measures must be taken to prevent a malfunction of the handwheel which could cause danger to human beings or damage to operating equipment. Correct use The EUCHNER handwheel is a universal pulse generator for manual shaft positioning. The handwheel is primarily used for positioning NCdriven machine tools during set-up. Handwheels are used as part of an overall higherlevel control system. Their use, installation and operation are permissible only in conformity with these Operating Instructions. Incorrect use Handwheels on their own must not be used as safety components for avoiding hazardous states in a machine installation. Function Two square-wave outputs of 100 or 25 pulses per revolution are available for the user. A second output phase-shifted by 90° allows the connected control to detect the direction of movement. The pulses are evaluated in the control. The detent mechanism is magnetic and is therefore totally wear-free. Assembly The unit may only be assembled by authorised personnel. Do not open the handwheels! Do not throw or drop the handwheels! Do not hit the handwheels! Do not use tools on the handwheels! The handwheel is assembled with nuts on 3 threaded M3 bolts. Fig. 1: Assembly of handwheel HKA/HKC Electrical connection Electrical connection may only be performed by authorised personnel trained in EMC with the machine switched off and in de-energised state. The machine must be safeguarded against reactivation. If connected incorrectly, the handwheel may be damaged. Observe electrical characteristics and the pin assignments (see technical data) Always shield connecting leads. Apply shielding to handwheel screw terminal pin . Ground the shield at the end of the lead at a central grounding point, e.g. in the distribution board or in the control cabinet, over a large surface, with low resistance and with low inductance. Do not install connecting leads in the immediate vicinity of interference sources. When installing connections, the operator must ensure compliance with the EMC safety requirements. Authorisation according to : operation with power supply of UL-class 2 only, housing type UL-type 1. Service and inspection EUCHNER handwheels require no maintenance. Handwheels may only be repaired by the manufacturer. To clean the handwheels, only use solvent-free cleaning agents and a soft cloth. Disclaimer of liability The company does not accept liability regarding the following cases: if the unit is not used for its intended purpose if the safety instructions are not followed if the units are electrically connected by unauthorised personnel if the units are tampered with Instructions for counting the handwheel pulses: Handwheel HKA100 and HKC100 In the home position (detent position), outputs A and B are both in the LOW state. A B a When it moves clockwise, the home position area is located closer to the rising edge of A (distance b) than when it moves counter-clockwise (distance a). b Home position area Using a counting method which counts with the edge of the output and uses the other output for detecting the direction of rotation can result in sensitive behaviour in one direction. A B Suitable counting methods The following options are recommended for counting the handwheel pulses: suitable counter module phase discriminator Count with the edge of A Ascending falling edge from A and HIGH level at B Descending a rising edge from A and HIGH level at B or Count with the edges of B Ascending rising edge from B and HIGH level at A Descending falling edge from B and HIGH level at A Note for A05 and A12: If the recommended counting method does not function properly, the signal behavior may be remedied by changing the following connection: Handwheel signal A Counter module input /A Handwheel signal/A Counter module input A Handwheel signal B Counter module input/B Handwheel signal/B Counter module input B Unsuitable counting methods Never use critical pulse edges for counting! On its own, the occurrence of a pulse edge must not result in movement, e.g. of a machine component. Care must be taken to ensure that the counter does not increment until the position of the handwheel has actually changed. Counting with the rising/falling edge of A - where B assists the direction detection (and vice versa) - is not suitable, because a pulse edge may be triggered by a slight rotation even though the handwheel has not yet reached the next detent position. A pulse edge is triggered by slight rotation even though the next detent position has not yet been reached. Instructions for counting the handwheel pulses: Handwheel HKA025 and HKC025 In the home position area, the two output signals assume the following states in sequence. A B Suitable counting methods The following options are recommended for counting the handwheel pulses: suitable counter module phase discriminator a Home position areas Uncritical pulse edges
