Setting parameters
Parameter Function Setting
P1055[0...2] BI: Enable JOG right This parameter defines source of JOG right when P0719 = 0
(Auto selection of command / setpoint source).
Factory default: 19.8
P1056[0...2] BI: Enable JOG left This parameter defines source of JOG left when P0719 = 0
(Auto selection of command / setpoint source).
Factory default: 0
P1057 JOG enable = 1: Jogging is enabled (default)
P1058[0...2] JOG frequency [Hz] This parameter determines the frequency at which the inverter
will run while jogging is active.
Range: 0.00 ... 599.00 (factory default: 5.00)
P1059[0...2] JOG frequency left [Hz] This parameter determines the frequency at which the inverter
will run while JOG left is selected.
Range: 0.00 ... 599.00 (factory default: 5.00)
P1060[0...2] JOG ramp-up time [s] This parameter sets jog ramp-up time which is used while
jogging is active.
Range: 0.00 ... 650.00 (factory default: 10.00)
P1061[0...2] JOG ramp-down time [s] This parameter sets jog ramp-down time which is used while
jogging is active.
Range: 0.00 ... 650.00 (factory default: 10.00)
5.6.2.3 Setting the voltage boost
Functionality
For low output frequencies, the V/f characteristics only give a low output voltage. The ohmic
resistances of the stator winding play a role at low frequencies, which are neglected when
determining the motor flux in V/f control. This means that the output voltage can be too low in
order to:
● implement the magnetization of the asynchronous motor
● hold the load
● overcome losses in the system.
The output voltage can be increased (boosted) in the inverter using the parameters as
shown in the table below.
