Description of the digital outputs
No function assigned.
0, Off
1, v_act<x
As long as the absolute value for the motor speed is lower than a preset value (auxiliary value "x"), a
HIGH-signal will be output. After the function has been selected you can enter the speed in rev./min. as the
auxiliary value "x".
2, v_act>x
As long as the absolute value for the motor speed is higher than a preset value (auxiliary value "x"), a
HIGH-signal will be output. After the function has been selected, you can enter the speed in rev./min. as the
auxiliary value "x".
3, Mains-RTO
This signals the operational readiness of the amplifiers power output stage. After switching on the mains supply,
a LOW-signal is output until the DC-link circuit is fully charged up. A HIGH-signal is output when the charging of
the DC-link circuit is finished. If the DC-link voltage falls below 100V, then 0V will be output. The "Undervoltage"
monitoring is inactive.
4, Regen off
Signals if the preset regen power (screen page "Basic Setup") is exceeded.
This produces a HIGH-signal if a software limit-switch is reached (a preset function of the
5, Sw_limit
corresponding position register, set to "SW limit-switch 1" or "SW limit-switch 2" – the function is defined in the
screen page "Position Data").
If the position (angular position of the motor shaft) exceeds a preset value (auxiliary value "x"),
6, Pos.>x
a HIGH-signal will be output. After the function has been selected, you can enter the signaling position in
increment (a number or fraction of motor turns N) as the auxiliary value "x".
Make the calculation according to the following equation:
Maximum possible entry value: x = 2
When the target position for a motion task has been reached (the InPosition window), this is
7, InPos
signaled by the output of a HIGH-signal. A cable break will not be detected.
The width of the InPosition window for all the valid motion tasks is entered in the Position Data screen page.
If a sequence of motion tasks is performed one after another, then the signal for reaching the final position of
the motion-task sequence will be output (target position of the last motion task).
Signaling that the target position of each motion task has been reached, in a sequence of motion tasks, can be
achieved with the function "16, Next_InPos".
8, I_act<x
The output is a HIGH-signal, as long as the absolute r.m.s. value of the actual current is lower than a defined
value in mA (auxiliary value "x").
After the function has been selected, you can enter the current value as the auxiliary value "x".
The output is a HIGH-signal, as long as the absolute r.m.s. value of the actual current is higher than a defined
9, I_act>x
value in mA (auxiliary value "x").
After the function has been selected, you can enter the current value as the auxiliary value "x".
