If Reference Offset Select (01.009) = 0 then Reference Selected (01.001) is the selected reference multiplied by [1 + Percentage Trim (01.038) / 100.00)].

If Reference Offset Select (01.009) = 1 then the Reference Offset (01.004) is added to the selected reference to give Reference Selected (01.001).

If Reference Offset Select (01.009) = 2 then Reference Selected (01.001) is the selected reference plus the maximum output frequency multiplied by (Percentage Trim (01.038) / 100.00).

If Negative Reference Clamp Enable (01.008) = 1 then Minimum Reference Clamp (01.007) is forced to be a negative value and is applied to the final reference as the negative limit. If Negative Reference Clamp Enable (01.008) = 0 then - Maximum Reference Clamp (01.006) is applied to the final reference as the negative limit. (If Select Motor 2 Parameters (11.045) = 1 then M2 Minimum Reference Clamp (21.002) is used instead.)

The minimum reference clamp is also used to provide the minimum frequency limit for uni-polar mode (i.e. Bipolar Reference Enable (01.010) = 0) after the Reference Selected (01.001) as shown in Fig.1.2.

See Control Word Enable (06.043) which will take priority over Reference Selector (01.014).

If Drive Configuration (11.034) i sset to 8 then Reference Selector (01.014) is automatically set to 4.

Reference Selector (01.014) defines how Reference Selected Indicator (01.049) is derived. If 0 Reference Selector (01.014) Reference Selected Indicator (01.049) is equal to Reference Selector (01.014). If Reference Selector (01.014) = 0 then Reference Selected Indicator (01.049) is controlled by the reference select flags as shown below. The higher numbered flags have priority over the lower numbered flags.

All reference select flags equal to 0 | 1
Reference Select Flag 1 (01.041) = 1 | 2
Reference Select Flag 2 (01.042) = 1 | 3
Reference Select Flag 3 (01.043) = 1 | 4

Preset Selector (01.015) defines how Preset Selected Indicator (01.050) is derived as shown below.

When Preset Selector (01.015) = 0 then Preset Selected Indicator (01.050) is defined by the preset select flags as shown below.

If Reference Selected Indicator (01.049) = 4 the Keypad Control Mode Reference (01.017) is used and the sequencer operates in keypad mode where the start and stop functions are provided from the drive keypad. Jog Select (01.013) is always 0 when keypad mode is active.

If Preset Selector (01.015) = 9 then Preset Selected Indicator (01.050) is incremented by one at intervals defined by Preset Selector Timer (01.016). When Preset Selected Indicator (01.050) has a value of 8 and is incremented it rolls over to 1. If Preset Selector Timer Reset (01.048) = 1 and Preset Selector (01.015) = 9, then Preset Selected Indicator (01.050) is held at 1.

The skip references functions are available to prevent continuous operation within a specified frequency range (i.e. where mechanical resonance may occur). When Skip Reference 1 (01.029) = 0 Filter 1 is disabled. Skip Reference Band 1 (01.030) defines the range either side of Skip Reference 1 (01.029) over which references are rejected in either direction. The actual rejection band is therefore twice that defined by Skip Reference Band 1 (01.030) with Skip Reference 1 (01.029) as the centre of the band. When the selected reference is within the rejection band the lower limit of the band is passed through the filter so that reference is always less than demanded.

Filter 2 (Skip Reference 2 (01.031), Skip Reference Band 2 (01.032)) and Filter 3 (Skip Reference 3 (01.033), Skip Reference Band 3 (01.034)) operate in the same ways as Filter 1.

If any of the filters are active (i.e. the reference is within their rejection band) Reference In Rejection Zone (01.035) is set to 1, otherwise it is 0.
