(P1082 . 60 / r0313) RPM /
Acts on P1082 (243AH*). When this object
changes, this effects the gradient (rate-of-fall)
of the down ramp.
U32 / 15 000/
rw
RPM in 100 s /
When reading-out the object the value in
subindex 1 is calculated using P1120, P1082
and the pole pair number according to the
following formula:
⋅
P1082 100 s
∆ =
n
⋅
P1120 r0313
After each power-up, this subindex is set to
the speed at which the drive rotates in 100 s. If
subindex 1 or 2 are changed, then this effects
P1120.
(2070H*)
U16 / 100 s /
rw After every power-up, this subindex is set to
the default value of 100 s.
U32 / 15 000/

RPM in 100 s /
When reading-out the object the value in
subindex 1 is calculated using P1121, P1082
and the pole pair number according to the
following formula:
⋅
P1082 100 s
∆ =
n
⋅
P1121 r0313
After each power-up, this subindex is set to
the speed at which the drive rotates in 100 s. If
subindex 1 or 2 are changed, then this effects
P1121
(2071H*)
U16 / 100 s /

Using this object, the reference velocity to
convert the process quantities is set. This
object writes or reads from P2000 (27D0H*),
converted to RPM.
