Functions Common to All the Control Modes
P0217 – Zero Speed Disable
Adjustable
Range:
Proprieties:
Access groups
via HMI:
Description:
When ON, it disables the inverter after the speed reference (N*) and the actual speed (N) become lower than the
value adjusted in the parameter P0291.
The inverter is enabled again when one of the conditions defined by the parameter P0218 is satisfied.
DaNGeR!
Be careful when approaching the motor while it is in the disable condition. It may get back to
operation at any moment because of the process conditions. In case you want to handle or perform
any type of maintenance, remove power from the inverter.
P0218 – condition to Leave the Zero Speed Disable
Adjustable
Range:
Proprieties:
Access groups
via HMI:
Description:
It specifies if the condition to leave the zero speed disable will be only the speed reference or also the actual speed.
When the PID regulator is active (P0203=1) and in Automatic mode, for the inverter to leave the disable condition,
besides the condition programmed in P0218, it is also necessary that the PID error (the difference between the
Setpoint and the process variable) be higher than the value programmed in P0535. Refer to the section 20.6 for
more details.
