Time ramps
During operation, you can switch over from the time ramps confi-
gured under PNU F02 and F03 to those configured under PNU A92
and A93. This can be done either by applying an external signal to
input 2CH at any time or when the frequencies configured under
PNU A95 and A96 are reached.

characteristic
– Here, you can set a linear or an S-curve acceleration characteristic for motor acceleration
(first and second time ramp):
00
00 Linear acceleration of the motor from the first to the second time
ramp
