Second time ramp 2CH
If the digital input which has been configured as 2CH is active, the
motor will be accelerated or braked with the second acceleration
or deceleration time. If the 2CH input is again deactivated, a chan-
geover to the first acceleration/deceleration time takes place.
X Set under PNU A92 and PNU A93, the required value for the
second acceleration and delay time.
X Then set under PNU A94, the value 00 so that the changeover
to the second acceleration and delay time via the 2CH input is
enabled (this is the default setting).
X Program one of the digital inputs 1 to 5 as 2CH, by setting the
value 09 under the respective PNU (C01 to C05).

01 Changeover to the second time ramp when the frequencies entered under
PNU A95 and/or A96 are achieved
h
If you set PNU A94 to 01, the changeover to the second
acceleration or deceleration time can take place auto-
matically at the frequency set under PNU A95 or A96
(a Section ”Time ramps”, Page 96).
h
The value for the first acceleration and deceleration time
is defined in PNU F01 and F02 (a Section ”Acceleration
time 1”, Page 76).
