● 15: Logic control deactivated
Used to control the operation of logic control.
[E2.21] Xi = 15 Logic control status
≠ 0 OFF Running (Factory default)
≠ 0 On Inactive
= 0 OFF Inactive
= 0 On Inactive
Tab. 7-12: Logic control status
● 16: Logic control paused
When the digital input is of On, the logic control is paused and the fre‐
quency converter runs at zero speed; when the digital input is of OFF,
the frequency converter resumes the status before the logic control
pause.
● 17: Switch between speed control and torque control
Used to switch between speed control and torque control in vector con‐
trol with feedback. The related parameter is S1.04.
– When parameter [S1.04] = 0, the digital input is disconnected to
activate speed control; and when the digital input is connected to
activate torque control.
– When parameter [S1.04] =1, torque control is always on regardless
of the status of the digital inputs.
● 18: Switch between VR1 analog reference and +I analog reference
The switching rule is shown in table below.
