For safety reasons, applications that may be
affected by the operation status of the drive should
be set up so that operation can only occur when the drive is ready to operate. A "Drive ready"
and "Fault" signal should be assigned to the multi-function outputs to guarantee interlock with
application.
u
Drive Ready Signal
The "Drive ready" signal is output to one of the multi-function terminals after the drive has
booted up and there is no fault present. It indicates that the drive is ready for operation.
• The power is off.
• A fault situation is present.
• There is a problem with the drive internal power supply.
• Parameter settings restrict a Run command from being entered.
• An overvoltage or undervoltage situation is present so that when the Run command is given
a fault is immediately triggered.
• The drive is in the programming mode and parameter settings restrict a Run command from
being entered in the programming mode.
