Description of parameters
1001
Number of auxiliary drives
7
187(209)
(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 converter 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 121.
1003
Stop frequency, auxiliary drive 1
7
(2.9.3)
The frequency of the drive controlled by the frequency converter 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 converter is dropped after starting the auxiliary drive. See
Figure 8-54.

Start delay of auxiliary drives
The frequency of the drive controlled by the frequency converter 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 converter 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.
