SINAMICS V20 Converter
258 Operating Instructions, 10/2019, A5E34559884-012
Defines command source of dual ramp enable command. If binary input is equal to one, then the dual
ramp will be applied. This works as follows:
• Ramp-up:
– Converter starts ramp-up using ramp time from P1120
– When f_act > P2157, switch to ramp time from P1060
• Ramp-down:
– Converter starts ramp-down using ramp time from P1061
– When f_act < P2159, switch to ramp time from P1121
See P2150, P2157, P2159, r2198.
The dual ramp algorithm uses r2198 bits 1 and 2 to determine (f_act > P2157) and (f_act < P2159). P2150
is used to apply hysteresis to these settings, so the user may wish to change the value of this parameter
to make the dual ramp function more responsive. It is not recommended that the dual ramp function is
used in conjunction with JOG ramp.
