－ 51 －－ 50 －• Jog operationThe motor runs in one direction at a specified speed as long as the signal is on.Jog operation is allowed even when homing is not completed.Set Pr50 to 53 as follows, and assign the function of signal input.Of signal inputs 1 to 4 (I1 to I4), set the input used for forward jog operation instruction at “4”,and the input used for reverse jog operation instruction at “5”.The motor runs in specified direction as long as specified input signal is on.When the input signal is turned off, the motor reduces its speed and stops.See Pr4b to 4d for parameters relating to jog operation.[Timing chart of jog operation]MAX 10 msJog signal (input)Commanded speedIn-motion signal(output)OFF OFFONOFFOFF ON(1) Change the jog start signal from contact-off to the status of connection to GND (on).It activates operation.(2) When the jog start signal is returned to off, the motor starts speed reduction.(3) When operation is completed, the transistor of in-motion signal (BUSY) returns to off.• Operation instruction can be given to the motor only when in-motion signal is off.• In jog operation, setting of Pr20 is applied to acceleration and deceleration pattern(linear and S-letter) as for acceleration. In deceleration, the pattern is linear irrespec-tive of setting of Pr21.When the 1st point (or the 3rd point) is set by absolute travel, if the motor passes theposition designated by parameter, the motor speed changes to the speed set by the 2ndpoint (or the 4th point), and the motor runs to the target position. In relative travel, themotor runs by the speed designated at the 1st point (or the 3rd point) for the distance setby the 1st point (or the 3rd point) from run start, and then the motor speed changes tothe speed designated at the 2nd point (or the 4th point) and the motor runs to the targetposition.e.g.) When the 1st point and the 2nd point are set to combined block operation (Pr06 = 2)Commanded speed[1] When the 1stspeed settingthe 2nd speedsetting [2] When the 1stspeed settingthe 2nd speedsettingS1S1S2S2P1 P1P2 P2Run start signal(input)In-motion signal(output)S1: The 1st speed setting set by the 1st pointP1: The 1st positionS2: The 2nd speed setting set by the 2nd pointP2: The 2nd positionONOFFONOFFOFF ONOFFONOFFOFF OFFOFF• When the 1st point position > the 2nd point position (when the target position is closerthan the position to change speed setting (P1)), the motor runs to the 2nd point posi-tion at the 1st speed setting and positioning operation is completed.• When the motor run start position has already passed the position of the 1st pointsuch as when the motor is stopped halfway (or when the operation direction to the 1stpoint is different from that to the 2nd point), the motor runs to the position of the 2ndpoint at the 2nd speed setting, and positioning operation is completed.• During combined block operation, data of the 1st point is applied to the setting of ac-celeration and deceleration time. Setting at the 2nd point is made ineffective, and themotor operates with acceleration and deceleration time set at the 1st point.• In combined block operation, acceleration and deceleration pattern is fixed to linearity.(It is the same when the motor runs to the target position at a constant speed.)• In combined block operation (status where the 1st block setting is “2”), when the 2ndpoint positioning command is executed, command execution error (E-rU) isfound.• When using block setting “2” and “1” together, it is enabled by setting the block settingparameter at “1” and setting the block timer at the 2nd point. (Operation at the 3rd pointis started after completion of combined block operation at the 1st point + the 2nd point.)Detail of parameters
