8.2.11 Digital Outputs
P3.5.3.2.1 RO1 function
Selection Selection name Description
0 None Output not used
1 Ready The AC drive is ready to operate
2 Run The AC drive operates (motor is running)
3 General fault A fault trip has occurred
4 General fault inverted A fault trip has not occurred
5 General alarm An alarm has been initiated
6 Reversed The reverse command has been given
7 At speed The output frequency has reached the set frequency reference
8 Thermistor fault A thermistor fault has occurred.
9 Motor regulator activated
One of the limit regulators (e.g. current limit, torque limit) is
activated
10 Start signal active Drive start command is active.
11 Keypad control active Keypad control selected (active control place is keypad).
12 I/O control B active I/O control place B selected (active control place is I/O B)
13 Limit supervision 1 Activates if the signal value falls below or exceeds the set
supervision limit (P3.8.3 or P3.8.7) depending on the selected
function.
14 Limit supervision 2
15 SinglePowerOn
Single PO (Power On) Threshold can be used to set level for
RO1 or RO2 to switch off when DC voltage goes below the
setting level.
The relay function must be programmed as 15/Single Power On.
Relay can be used to control to connect additional resistor into
DC supply. Resistor will eliminate power on/off cycle when supply
voltage drops into drive shut down level. Resistor size can be
selected approximately equal to drive standby losses.
16 No function
17 Preset speed active The preset frequency has been selected with digital input signals.
18 No function
19 PID in Sleep mode PID-controller is in Sleep mode.
20 PID Soft Fill activate PID-controller Soft Fill function is activated.
21 PID supervision limits PID-controller feedback value is beyond the supervision limits.
22 Ext PID supervision limits
External PID-controller feedback value is beyond the supervision
limits.
23 Input press. alarm/fault
The input pressure signal value of the pump has fallen below the
value defined.
24 Frost prot. alarm/fault
25 No function
26 No function
27 No function
