● k1: VR1 channel amplification factor, see parameter E0.10.
● k2: VR2 channel amplification factor, see parameter E0.11.
● k3: +I channel amplification factor, see parameter E0.12.
● 19: External fault N.O. contact input
● 20: External fault N.C. contact input
When an external fault signal is sent to the frequency converter, the fre‐
quency converter responses with ‘E.-St’ alarm and stops. This is to facil‐
itate the monitoring and interlinking of the external devices.
● 21: External Reset input
– Same like reset by operating panel.
– Allows remote fault reset.
● 22: Activate communication control
– Used to switch between control by operating panel and by commu‐
nication, when [b1.02] = 0.
– Used to switch between control by digital inputs and by communi‐
cation, when [b1.02] = 1.
● 23: Torque limit set by VR1 enabled
Used to enable the VR1 analog channel to set the torque limit when the
frequency converter works in speed mode.
VR1, 0...10 V corresponding torque: 0...200 %
● 24: Torque limit set by VR2 enabled
Used to enable the VR2 analog channel to set the torque limit when the
frequency converter works in speed mode.
VR2, 0...10 V corresponding torque: 0...200 %
● 25: Forward jogging
Used to enable forward jogging.
● 26: Reverse jogging
Used to enable reverse jogging.
The logic relation between forward / reverse jogging frequency and run‐
ning frequency is shown as below:
