Par
Mod
Add Description Def Min Max Unit R/W
2-01 201 Start Speed 1 (rps) 30 P1-02 Rps R/W
Start-up sequence speed 1. If Start Speed 1 Time (P2-02) is greater than zero, the drive will ramp up to the
speed set in this parameter for the time set in P2-02 on each start-up. If the time set in P2-02 is zero, this section
of the start-up sequence is ignored.
2-02 202 Start Speed 1 Time 60 0 600 s R/W
This time is the time that the drive will sit at Start Speed 1 on each start-up. This section of the start-up sequence is
disabled if this time is set to zero.
2-03 203 Start Speed 1 Acceleration Ramp 30 0 6000 s R/W
This is the acceleration ramp used to ramp up from 0 rps to Start Speed 1 if the function is enabled. Ramp rate is
defined as time to get to rated speed from zero speed.
2-04 204 Start Speed 2 (rps) 30 P1-02 Rps R/W
Start-up sequence speed 2. If Start Speed 2 Time (P2-05) is greater than zero, the drive will ramp up to the
speed set in this parameter for the time set in P2-05 on each start-up. If the time set in P2-05 is zero, this section
of the start-up sequence is ignored.
2-05 205 Start Speed 2 Time 60 0 600 s R/W
This time is the time that the drive will sit at Start Speed 2 on each start-up. This section of the start-up sequence is
disabled if this time is set to zero.
2-06 206 Start Speed 2 Acceleration Ramp 30 0 6000 s R/W
This is the acceleration ramp used to ramp up from Start Speed 1 up to Start Speed 2 if the function is enabled
Ramp rate is defined as time to get to rated speed from zero speed.
2-07 207 Start Speed 3 (rps) 30 P1-02 Rps R/W
Start-up sequence speed 3. If Start Speed 3 Time (P2-08) is greater than zero, the drive will ramp up to the
speed set in this parameter for the time set in P2-08 on each start-up. If the time set in P2-08 is zero, this section
of the start-up sequence is ignored.
2-08 208 Start Speed 3 Time 60 0 600 s R/W
This time is the time that the drive will sit at Start Speed 3 on each start-up. This section of the start-up sequence is
disabled if this time is set to zero.
2-09 209 Start Speed 3 Acceleration Ramp 30 0 6000 s R/W
This is the acceleration ramp used to ramp up from Start Speed 2 to Start Speed 3 if the function is enabled.
Ramp rate is defined as time to get to rated speed from zero speed.
2-10 210 Minimum Off Time 0 0 6000 s R/W
This parameter when set greater than 0, defines the minimum time that the drive must be stopped for before
allowing a re-start. The remaining time before the drive can start is available in P0-16.
NOTE This time is valid also from first power-up.
2-11 211 Minimum On Time 0 0 6000 s R/W
This parameter when set greater than 0, defines a minimum time that the drive must run for once it has started,
it will delay a stop command if the time set in this parameter has not elapsed. Please note that if the drive is
configured for Coast to stop (P1-05 = 1) or if the drive is below minimum speed when the stop command is
issued , this function will be ignored. The STO input overrides this function. The remaining time before the drive
can be stopped is available in P0-17
2-12 212 Re-start Delay 0 0 6000 s R/W
This parameter configures the minimum time between each compressor starts. Any start command requests given
to the drive before the time set in this parameter has elapsed will be ignored until the Re-start delay time has been
observed. The remaining time before the next permitted start can be seen in P0-18.
