Second time ramp (2CH)
If the digital input configured as 2CH is active, the motor is
accelerated 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 5 as 2CH, by setting the
corresponding PNU (C001 to C005) to 09.

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
automatically at the frequency set under PNU A095 or
A096 (
a
section “Time ramps”, page 129).
h
The value for the first acceleration and deceleration time
is defined in PNU F001 and F002 (
a
section
“Acceleration time 1”,page 105).
