Jog properties
S If both jog signals are issued at the same time, the current speed is maintained
(constant velocity phase).
S Jog setpoints are approached and exited via the ramp-function generator.
S The jog function can be activated from the "ready to start" status and from the
OFF1 deceleration ramp.
S If ON/OFF1 = "1" and jog are selected simultaneously, ON/OFF1 has priority.
S OFF2 and OFF3 have priority over jogging.
S If the ON/OFF1 command is present after the jog signal has been removed
(ON/OFF1 = 1), the "normal" speed setpoint is activated via the ramp-function
generator.
S In jog mode, the main speed setpoints (r1078) and the supplementary setpoints
1 and 2 (p1155 and p1160) are inhibited.
S The suppression bandwidths (p1091 ... p1094) and the minimum limit (p1080)
in the setpoint channel are also active in jog mode.
S In jog mode, ZSWA.02 (operation enabled) is set to "0" because the speed
setpoint has not been enabled for control.
S The ramp-function generator cannot be frozen (via p1141) in jog mode
(r0046.31 = 1).
