[. . . ] FANUC Series 0 -MC * OPERATOR'S MANUAL B-64124EN/01 No part of this manual may be reproduced in any form. All specifications and designs are subject to change without notice. The export of this product is subject to the authorization of the government of the country from where the product is exported. In this manual we have tried as much as possible to describe all the various matters. However, we cannot describe all the matters which must not be done, or which cannot be done, because there are so many possibilities. Therefore, matters which are not especially described as possible in this manual should be regarded as "impossible". SAFETY PRECAUTIONS This section describes the safety precautions related to the use of CNC units. [. . . ] 7100) enables or disables the manual handle feed in the TEACH IN JOG mode. D Availability of manual pulse generator in TEACH IN JOG mode (THD) D A command to the MPG exceeding rapid traverse rate (HPF) Parameter HPF (bit 4 of No. 7117) specifies as follows: D Parameter HPF (bit 4 of No. 7100) Set value 0 : The feedrate is clamped at the rapid traverse rate and generated pulses exceeding the rapid traverse rate are ignored. (The distance the tool is moved may not match the graduations on the manual pulse generator. ) Set value 1 : The feedrate is clamped at the rapid traverse rate and generated pulses exceeding the rapid traverse rate are not ignored but accumulated in the CNC. (No longer rotating the handle does not immediately stop the tool. The tool is moved by the pulses accumulated in the CNC before it stops. ) D Parameter HPF (No. 7177) (It is available when parameter HPF is 0. ) Set value 0 : The feedrate is clamped at the rapid traverse rate and generated pulses exceeding the rapid traverse rate are ignored. (The distance the tool is moved may not match the graduations on the manual pulse generator. ) Other than 0 : The feedrate is clamped at the rapid traverse rate and generated pulses exceeding the rapid traverse rate are not ignored but accumulated in the CNC until the limit specified in parameter No. (No longer rotating the handle does not immediately stop the tool. The tool is moved by the pulses accumulated in the CNC before it stops. ) Parameter HNGx (No. 7102 #0) switches the direction of MPG in which the tool moves along an axis, corresponding to the direction in which the handle of the manual pulse generator is rotated. D Movement direction of an axis to the rotation of MPG (HNGX) 470 B64124EN/01 OPERATION 3. MANUAL OPERATION Restrictions D Number of MPGs Up to three manual pulse generators can be connected, one for each axis. The three manual pulse generators can be simultaneously operated. WARNING Rotating the handle quickly with a large magnification such as x100 moves the tool too fast. The feedrate is clamped at the rapid traverse feedrate. NOTE Rotate the manual pulse generator at a rate of five rotations per second or lower. If the manual pulse generator is rotated at a rate higher than five rotations per second, the tool may not stop immediately after the handle is no longer rotated or the distance the tool moves may not match the graduations on the manual pulse generator. 471 3. MANUAL OPERATION OPERATION B64124EN/01 3. 5 MANUAL ABSOLUTE ON AND OFF Whether the distance the tool is moved by manual operation is added to the coordinates can be selected by turning the manual absolute switch on or off on the machine operator's panel. When the switch is turned on, the distance the tool is moved by manual operation is added to the coordinates. When the switch is turned off, the distance the tool is moved by manual operation is not added to the coordinates. Y axis P2 Manual operation P1 O X axis The coordinates values change by the amount of manual operation. 3. 5 (a) Coordinates with the switch ON Y2 Y1 P2 O2 P1 X2 O1 X1 The coordinates do not change. 3. 5 (b) Coordinates with the switch OFF 472 B64124EN/01 OPERATION 3. MANUAL OPERATION Explanation The following describes the relation between manual operation and coordinates when the manual absolute switch is turned on or off, using a program example. G01G90 X100. 0Y100. 0F010 X200. 0Y150. 0 X300. 0Y200. 0 ; ; ; The subsequent figures use the following notation: Movement of the tool when the switch is on Movement of the tool when the switch is off The coordinates after manual operation include the distance the tool is moved by the manual operation. [. . . ] LED display Description The control circuit is not operating normally. Countermeasure (1) Check the 24VDC control supply voltage. If the voltage is low, increase the voltage to an appropriate level. (2) Check whether a fuse in the servo amplifier unit has blown. [. . . ]
