378 Configuration
1. SLS request is activated (
= DI X113:2 & X114:2). SLS time
delay monitoring is started (
= 2000 ms). Deceleration to
SLS limit speed is started (23.13 Deceleration time 1).
2. Modulation is lost. Motor starts to coast to a stop. SLS time monitoring limit is kept
active also when modulation is lost (
= 2000 ms). Modoff
delay time starts to run (
= 200 ms).
3. Modulation of the drive has not returned before the SLS ramp modoff delay time
has elapsed (
SSE function (
) as the modulation is lost. SSE function
triggers STO function regardless of the configuration of the SSE function. STO
indication goes on (
= DO X113:7).
4. SLS time monitoring limit (
= 2000 ms).
5.
delay starts when drive modulation is lost. If modulation does not return,
SLS indication goes on after
delay has elapsed.
Example 2
: The figure below shows an example of the modoff situation with SLS
function with time monitoring when "Monitoring active" (parameter
) is
selected:
• Basic parametrization of the SLS function made according to chapter
.
• Monitoring active when drive modulation is lost (
