The determination of whether the Preset Speed 1 will be the Frequency Reference 1 (d1-01 or the analog input A1) is
determined by the status of b1-01. If b1-01= “1: Terminals”, the value of the input to A1 will determine the commanded speed
when Preset Speed 1 is selected. If b1-01
≠
1, the setting of d1-01 will determine the commanded speed when Preset Speed 1 is
selected.
The determination of Preset Speed 2 is made much the same way as Preset Speed 1 except that the setting of parameter H3-09
decides whether the analog input A2 or d1-02 is Preset Speed 2. If H3-09= “2: Aux Reference”, the value of the input to A2
will determine the commanded speed when Preset Speed 2 is selected. If H3-09
≠
2, the setting of d1-02 will determine the
commanded speed when Preset Speed 2 is selected.
Function: Jog Frequency Reference
Setting: 6
When a digital input configured as Jog Freq Ref (H1-0x= 6) is Closed, the active speed command will be the setting of
parameter d1-17 (Jog Frequency Reference). Closure of this digital input alone will not initiate a Jog motion, it will only
change the speed command. An active Run input is necessary for actual jogging.
To change to the Jog Speed Command and provide a Run Command, with a single input, please refer to digital input settings
“12” and “13”.
Function: Multi-Acc/Dec 1
Setting: 7
When a digital input configured as Multi-Acc/Dec 1 (H1-0x= 7) is OPEN the first set of acceleration/deceleration times
(C1-01 and C1-02) are active.
When a digital input configured as Multi-Acc/Dec 1 (H1-0x= 7) is CLOSED the second set of acceleration/deceleration times
(C1-03 and C1-04) are active.
