SEW Unit Profile
Control command
"Stop" The control command Stop will have the inverter brake the motor at the stop ramp. If
the process ramp is transmitted via the fieldbus system, this control command will use
the currently indicated ramp value as brake ramp. Else, the drive inverter uses the
typical integrator ramp for this control command depending on the set parameters and
integrator set.
The control command
stop is triggered with bit 2: Enable/stop .
Control command
"Enable" You enable the inverter via the fieldbus system with the control command Enable . If the
process ramp is transmitted via the fieldbus system, this control command will use the
currently indicated ramp value as brake ramp. Else, the drive inverter uses the typical
integrators
ramp up for this control command depending on the set parameters and in-
tegrator set.
All three bits must be set to
Enable (110
bin
) for the control command Enable .
Control command
"Hold control" Setting bit 3 to the value "1" lets you activate the hold control function is speed-controlled
operation. The function triggers a stop at the applicable integrator ramp with subsequent
hold control. In operating modes without speed feedback, this bit is not relevant and the
function is not activated.
Selecting the valid
parameter set The applicable parameter set is selected using bit 5 in the control word. A parameter set
can only be changed in
controller inhibit condition.
This bit is ORed with the input terminal function parameter set changeover . This means
the logical state "1" of the input terminal OR the control word bit activates parameter set
2.
Reset after an
error In case of an error, bit 6 of the control word will execute a reset via the process data
channel. A reset can only be triggered with a a 0/1 edge in the control word.
