190 Description of Parameters Honeywell
1001 Number of auxiliary drives 7 (2.9.1)
With this parameter the number of auxiliary drives in use will be defined. The functions
controlling the auxiliary drives (parameters ID458 to ID462) can be programmed to relay
outputs or digital output. By default, one auxiliary drive is in use and it is programmed to
relay output RO1 at B.1.
1002 Start frequency, auxiliary drive 1 7 (2.9.2)
The frequency of the drive controlled by the frequency drive must exceed the limit
defined with these parameters with 1 Hz before the auxiliary drive is started. The 1 Hz
overdraft makes a hysteresis to avoid unnecessary starts and stops. See Figure 8-54.
See also parameters ID101 and ID102, page 122.
1003 Stop frequency, auxiliary drive 1 7 (2.9.3)
The frequency of the drive controlled by the frequency drive must fall with 1Hz below the
limit defined with these parameters before the auxiliary drive is stopped. The stop
frequency limit also defines the frequency to which the frequency of the drive controlled
by the frequency drive is dropped after starting the auxiliary drive. See Figure 8-54.
1004 Start frequency, auxiliary drive 2 7 (2.9.4)
1005 Stop frequency, auxiliary drive 2 7 (2.9.5)
1006 Start frequency, auxiliary drive 3 7 (2.9.6)
1007 Stop frequency, auxiliary drive 3 7 (2.9.7)
1008 Start frequency, auxiliary drive 4 7 (2.9.8)
1009 Stop frequency, auxiliary drive 4 7 (2.9.9)
See ID’s 1002 and 1003.
1010 Start delay of auxiliary drives 7 (2.9.10)
The frequency of the drive controlled by the frequency drive must remain above the start
frequency of the auxiliary drive for the time defined with this parameter before the
auxiliary drive is started. The delay defined applies to all auxiliary drives. This prevents
unnecessary starts caused by momentary start limit exceedings. See Figure 8-54.
1011 Stop delay of auxiliary drives 7 (2.9.11)
The frequency of the drive controlled by the frequency drive must remain below the stop
limit of the auxiliary drive for the time defined with this parameter before the drive is
stopped. The delay defined applies to all auxiliary drives. This prevents unnecessary
stops caused by momentary falls below the stop limit. See Figure 8-54.
