Selec VFD Series

55
User Manual
The above parameters deal with the external communication feature of the drive. The parameter P11-00
defines the slave ID that will be assigned to the VFD. Note that the drive always acts as a slave in the
communication system. The parameter P11-01 defines the baud rate at which the communication
system will operate. P11-02 defines the MODBUS data format that will be used. Note that these
parameters need to be the same across all members of the communication system. The parameters
P11-04, P11-05, and P11-06 deal with customizable timeout settings for the
user. In systems where input is expected from the master device in every set period, this feature can be
used to generate a time-out action wherein one of the options from P11-06 will be performed. This action
will be triggered if no data is received from the master device in the time specified in P11-05. This feature
should be used only in cases where there is a continuous stream of data being transferred between the
drive and the master device. Otherwise, it could trigger an unnecessary fault.

These 2 parameters define the acc/dec times for the jogging operation. Note that these times are
also defined as the transition time between the Max Frequency as defined in (P0-08) to 0Hz.
