What it means
A07140 is issued with the text Drive: current controller sampling time for spindle does not match
. The drive raises this alarm when the current controller sampling time parameterized for the spindle has been set too high, so the set value does not match the maximum sampling time the drive permits for the spindle. That permitted maximum can be read from r5034, and the alarm is resolved by bringing the set sampling time down to this value or below it.
Why it appears
- The current controller sampling time parameterized for the spindle has been set too high.
- As a result, the set value lies above the spindle current controller sampling time maximum that the drive specifies in r5034.
What to check
- Read the maximum permissible sampling time for the spindle current controller from r5034.
- Set the sampling time equal to or less than this value; the manual names the sampling-time settings p0112 and p0115 together with this instruction.
Parameters the manual names
- r5034 (I_ctrl t_samp max) — shows the spindle current controller sampling time maximum: the value that the sampling time set for the spindle must be equal to or less than.
- p0112 (t_samp for p0115) — sampling times pre-setting: the sampling time that applies to p0115; one of the sampling-time settings named for this alarm.
- p0115 (t_samp suppl_fct) — sampling time for supplementary functions: the supplementary-function sampling time, named for this alarm together with p0112.
Acknowledging and restarting
No acknowledgment is required for this alarm. It is dealt with at the setting itself: set the sampling time equal to or less than the value in r5034 (p0112, p0115).

Questions technicians ask
What does alarm A07140 mean on a SINAMICS drive?
It reports that the current controller sampling time parameterized for the spindle has been set too high, so the set value does not match the maximum the drive permits for the spindle.
How do I fix alarm A07140?
Set the sampling time equal to or less than the value in r5034; the manual names p0112 and p0115 as the sampling-time settings for this.
Where is the maximum spindle current controller sampling time shown?
In r5034 — the spindle current controller sampling time maximum (I_ctrl t_samp max). The set sampling time must be equal to or less than this value.
Does A07140 have to be acknowledged?
No. No acknowledgment is required for this alarm; it is dealt with by correcting the sampling time setting itself.
