Controller enable
The axis is enabled with terminal 65. The controller and inhibit become effective
after 1 ms at the specific axes. If terminal 65 is inhibited, n
set
=0 is set for the
drive and it is braked as follows:
S For MSD/IMM 611A, the pulses are canceled after an adjustable speed has
been fallen below. The drive is braked along the selected ramp, or if terminal
81 is simultaneously inhibited, the drive is braked along the current limit.
S For FD 611A, all of the controllers and pulses are inhibited after the set ti-
mers have expired (setting when supplied:240 ms). The drives brake along
the current limit.
S For 611D/611U drives, the pulses are cancelled after a speed, which can be
set, is fallen below or after a selected timer has expired. The drive is braked
along the selected limits (MD 1230, 1235, 1238). For spindles, a ramp can
only be achieved using regenerative limiting (MD1237).
The 611D modules do not have a hard–wired terminal 65. The controller
enable is controlled using the NC/PLC interface signals via the digital drive
bus.
Signal contact, start inhibit
The NC contact closes, max. 40 ms after terminal 663 has been inhibited
Speed setpoint
Analog speed setpoint input: 0 to +/–10V
Differential input
Reference potential from terminal 56
Closed–loop current controlled operation
Switch setting = OFF “Ready signal”, switch position = ON “fault signal”
The ready signal from the 611A standard and resolver control acts centrally at
terminal 72–74, ready at the NE module, if:
S3.6= OFF “ready signal”,
a) There is no fault present in the drive module and
b) Terminal 65 and terminal 663 are enabled,
or for
S3.6 = ON “fault signal”
there is no fault present in the drive module.
Switch S6.6 for 2–axis versions has the same function as for S3.6.
