Unit Description / Notes
NOTES!
If the slack cable condition is detected during the stabilization
time, the motor remains at the stabilization speed until receiving
a "Stop" command. However, if this condition is detected outside
of the stabilization time, the output set to this option will be
deactivated and the motor will maintain the same speed.
The only way of disabling the Slack Cable function is stopping the
motor.
To a better understanding refer to figures 6.46 a) and b).
If P361 = 0 (Load Detection = Off) – the output always remains
activated.
- Torque Polarity +/-
The output programmed to this function will be activated when the torque
is positive.
- Torque Polarity -/+
The output programmed to this function will be activated when the torque
is negative.
NOTE!
The outputs that are set to the function "Torque Polarity" have a
hysteresis in its operation that can be configured at parameter P358
(Hysteresis for the Torque Current – Iq). This resource works in the
transition of these outputs at the moment they are activated or
deactivated.
