SINUMERIK 840D/SIMODRIVE 611 digital, HLA Module (FBHLA) - 10.03 Edition
Mode of operation when "Velocity controller enable" bit is set:
S
Valve setpoint is output by the velocity controller
S
I-component is enabled
S
Valve spool monitor is activated
If a velocity controller disable is requested, a zero velocity setpoint is output.
S
The braking time set in MD 5402 acts as a speed setpoint adjustment ramp
(acceleration limitation).
S
The setting in MD 5402 corresponds to the time required by the braking
ramp to decelerate the cylinder from the speed in MD 5401 down to zero.
This ramp is effective only when the velocity controller is disabled since, in
this case, the acceleration limits programmed in the control are ignored.
Otherwise, the control system has the responsibility of limiting acceleration
rates.
S
If velocity controller disable followed by a power disable is requested
(MD 5530 bit 3=0), then the delay set in MD 5404:
POWER_DISABLE_DELAY is left to run down after the velocity controller
disable request until the power disable signal is set. If MD 5530, bit 3=1,
MD 5404 has no meaning (drive continues to operate under closed-loop
control with a zero velocity setpoint following a velocity controller disable
request).

If the setup mode terminal (term. 112 on mains supply module) is selected, the
velocity setpoint is limited to the value programmed in MD 5420.

Only bits 2 and 4 are relevant for the user.
This LED indicates that the drive unit is ready (SIMODRIVE Ready terminal
