P1175[0...2] BI: Dual ramp
enable
This parameter defines command source of dual ramp enable command. If binary input
is equal to one, then the dual ramp will be applied. The factory default value is 0.
P1060[0...2] JOG ramp-up
time [s]
This parameter sets the JOG ramp-up time.
Range: 0.00 to 650.00 (factory default: 10.00)
P1061[0...2] JOG ramp-down
time [s]
This parameter sets the JOG ramp-down time.
Range: 0.00 to 650.00 (factory default: 10.00)
P1120[0...2] Ramp-up time [s] This parameter sets the time taken for motor to accelerate from standstill up to maximum
frequency (P1082) when no rounding is used.
Range: 0.00 to 650.00 (factory default: 10.00)
P1121[0...2] Ramp-down time
[s]
This parameter sets the time taken for motor to decelerate from maximum frequency
(P1082) down to standstill when no rounding is used.
Range: 0.00 to 650.00 (factory default: 10.00)
P2157[0...2] Threshold fre-
quency f_2 [Hz]
This parameter defines threshold_2 for comparing speed or frequency to thresholds.
Range: 0.00 to 550.00 (factory default: 30.00)
P2159[0...2] Threshold fre-
quency f_3 [Hz]
This parameter defines threshold_3 for comparing speed or frequency to thresholds.
Range: 0.00 to 550.00 (factory default: 30.00)
5.6.3.18 Setting the DC coupling function
Functionality
The SINAMICS V20 converter provides the facility to electrically couple two equal-size
converters together by using the DC link connections. The key benefits of this connection
are:
● Reducing energy costs by using regenerative energy from one converter as driving
energy in the second converter.
● Reducing installation costs by allowing the converters to share one common dynamic
braking module when needed.
● In some applications, eliminating the need for the dynamic braking module.
In the most common application, shown in the following figure, linking two SINAMICS V20
converters of equal size and rating allows the energy from one converter, presently
decelerating a load, to be fed into the second converter across the DC link. This requires
less energy to be sourced from the mains supply. In this scenario, the total electricity
consumption is reduced.
