Second time ramp 2CH
If the digital input configured as 2CH is active, the motor is acce-
lerated or braked with the second acceleration or deceleration
time. If the 2CH input is deactivated again, a changeover to the
first acceleration/deceleration time takes place.
X Under PNU A092 and PNU A093, set the required value for the
second acceleration and deceleration time.
X Then, set PNU A094 to 00 so that the changeover to the second
acceleration and deceleration time through the 2CH input is
enabled (this is the default setting).
X Program one of the digital inputs 1 to 8 as 2CH, by setting the
corresponding PNU (C001 to C008) to 09.
By default, 2CH is assigned to digital input 5.

Changeover

time ramp
– – 00 Changeover to the second time ramp if an active signal is
present at a 2CH digital input.
00
01 Changeover to the second time ramp when the frequencies
entered in PNU A095 and/or A096 are reached
h
If you set PNU A094 to 01, the changeover to the second
acceleration or deceleration time can take place auto-
matically at the frequency set under PNU A095 or A096
(a Section “Time ramps“, Page 148).
h
The value for the first acceleration and deceleration time
is defined in PNU F001 and F002 (a Section “Accelera-
tion time 1“, Page 121).
