[. . . ] The main drive is presumed to be set and calibrated to 10V command signal. Program valid revolutions S for each range, possibly near to the top revolution limit of the range and measure the revolution. The revolution can be specified by means of a tachometer or if the spindle is mounted with encoder from control current revolution display. The revolution calibration of each range can be done by overwriting parameters 512n S1 10Vn (n: range number) according to the below relation: 2 3 4 5 6 7 8 9 10 11 If exactly 10000 mV command signal must belong to the revolution specified at parameter 512n S110Vn, then set parameter 5021 ADJUSTS1 as described. If necessary set the rising and falling rate of analog spindle signal at parameters 504n S1ACCTn, 506n S1DECTn (n: range number). If the spindle is mounted with encoder and the PLC program applies flags I656 (n=nS) and I657 (n=0), then fill out parameters 5005 N%, 5006 NW, 5007 N0 as described. If the spindle is mounted with encoder and the PLC program applies flag I655 (spindle speed fluctuation function), then fill out parameters 5001 TIME, 5002 SCERR, 5003 FLUCT%, 5004 FLUCTW as described. If the spindle is mounted with encoder, then test thread cutting function. Write the following line to control by means of single block execution: G33 ZI­20 F1 S500 M3. If thread cutting is not started, then check if the PLC returns spindle rotation flag Y650=1 as well as rotation state RH062=3, or 4. If the spindle can be oriented (command M19), then set parameter 5281 ORIENT1 to 129 7. 6 Procedure of Spindle Parameter Setting 12 13 14 15 16 17 1. It is independent of the spindle being oriented mechanically or with closing position control loop since drilling cycles (G76, G87) demanding function M19 are executed only this way. the position control loop can be closed, then set parameter 5282 INDEX1 to 1. In this case set parameter 4469 NOLOOPS1 in SERVO parameter group to 0. S1 in SERVO parameter group as described in case of the set-up procedure of position control loop. Write function M19 in PLC program as described in the Sample PLC program. Set parameters 532n GAIN1n, 536n ACC1n (n: number of the range belonging to the different gears). Execute M19 as the effect of which the position control loop is closed. Thereafter the set-up procedure of spindle servo corresponds to that described in SERVO parameter group, except for values GAIN and ACC that can be specified for spindle for each range. It is practical to start the set-up procedure of position control loop at the lowest gear. 7. 6. 2 Setting Rigid Tapping (G84. 2, G84. 3) The main point in setting rigid tapping is that the proportion of the lag of drilling axis, e. g. axis Z (follow error, FOL. ERR) to thread rise must correspond to the proportion of the lag of spindle to the quadruple of spindle encoder pulse number. The quadruple of spindle encoder pulse number equals to 360° movement on spindle, i. e. [. . . ] 9182 MSPINT (BIT) 0: macro-type interrupt, 1: subprogram-type interrupt. 9183 TYPINT (BIT) 0: macro interrupt is also effective during block execution, 1: macro interrupt is only effective after block execution. 9184 ELT (BIT) 0: user macro interrupt is level-controlled, 1: user macro interrupt is edge-controlled. 9184 MCON (BIT) 0: the enabling and disabling of macro interrupt is executed by M96, M97, 1: the enabling and disabling of macro interrupt is executed by the M function specified at parameter MMION, MMIOFF.
