Module control
The following table lists the control signals used to start a movement.
Prerequisite: Drive enable [AF] = 1, Stop [STP] = 0,
Start enable [SFG] = 1
Mode (BA) Parameters Command /
Signal state
Activation of movement
Jogging (mode = 01) Velocity level
BP = 1 = level 1
BP = 2 = level 2
R+, R − /
Level
R+ or R − with “Level” = 1
(R+ and R − simultaneously error)
Control (mode = 02) Frequency level
BP = 1 = level 1
BP = 2 = level 2
R+, R − /
Level

(mode = 03)
− Start, R+, R − /
Edge
Direction as in MD
R+ or R − = 0/1 or Start = 0/1
(speed as in MD)
Incremental relative
(mode = 04)
BP = 1...100
BP = 254
R+, R − / Edge R+ = 0/1 or R = 0/1
(speed level 1)
MDI (mode = 06) − Start / Edge Start = 0/1 (R+, R − relevant only for rotary
axis with absolute measure specified for
direction selection)
Automatic
(mode = 08)
− Start / Edge Start = 0/1 (according to program preset-
ting)
Automatic single
block (mode = 09)
− Start / Edge Start = 0/1
Stat. pending start condition
“Processing in progress” remains active after the end of machining and there is no
start enable as long as the start condition is not reset.
