1144*
Default value
60
Move against fixed stop
Current setpoint which is to take effect as soon as speed control mode switches to current
control mode. The percentage that has to be entered refers to the max. motor current (drive
machine data MD 1104) and the possible reduction of the max. motor current (drive machine
data MD 1105). The holding torque can be matched still further in setting data SD 320*. See
functional description for "Travel to fixed stop"
1148*
Default value
500
If the max. speed as IKA partial setpoint is exceeded, interface signal "IKA/TKH SPEED" is set
in DB 32.
Speed tolerance endlessly turning rotary axis
1152*
Default value
10
If the actual speed of the "endlessly turning rotary axis" remains within the setpoint speed
tolerance defined in this machine data, interface bit "Axis in setpoint range" is set.
The tolerance monitoring is activated by switching on "Endlessly turning rotary axis" with
G[..]103 and G[..]104 and defining a new speed.
If movement is aborted in the mode group (Mode Group Ready = 0), an ERA does not have
to be explicitly reset with axis reset. ERA is reset with a mode group reset.
1156*-
D component feedforward control 2nd - 8th parameter set
1180*
Default value
0
This MD has the same meaning as MD 1124*, see also functional description of parameter set
switchover.
