Features
● If both jog signals are issued at the same time, the current speed is maintained (constant
speed phase).
● Jog setpoints are approached and exited via the ramp-function generator.
● Jog is possible from the "Ready to start" state.
● If ON/OFF1 = "1" and jog are selected simultaneously, ON/OFF1 has priority.
Therefore ON/OFF1 = "1" must not be active for jog to be activated.
● OFF2 and OFF3 have priority over jog.
● The switch-on command is issued via p1055 and p1056.
● The jog speed is defined via p1058 and p1059.
● The following applies in "Jog mode":
– The main speed setpoints (r1078) are disabled.
– The supplementary setpoint 1 (p1155) is disabled.
– The supplementary setpoint 2 (p1160) is forwarded and added to the current speed.
● The suppression bandwidths (p1091 to p1094) and the minimum limit (p1080) in the
setpoint channel are also active in jog mode.
● The ramp-function generator cannot be frozen (via p1141) in jog mode (r0046.31 = 1).
