Yaskawa E7L Drive Bypass - Manual (Page 143)

Programming 5 - 51
The following table details which reference is active based on the status of the Multi-step Ref 1 and Multi-step Ref 2 inputs:
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: Fault Reset
Setting: 14
Whenever the Drive detects a fault condition, the fault output contact will close and the Drive’s output will shut OFF causing
the motor to coast (specific stopping methods can be selected for some faults such as L1-04 for motor overheat). Once the Run
command is removed, the fault can be reset by either the RESET key on the digital operator or by closing a digital input
configured as a Fault Reset (H1-0x= 14).
Function: PI Disable
Setting: 19
When the PI Function has been enabled by b5-01 (PI Mode Selection), it can be indefinitely disabled by closing a digital input
configured as a PI Disable input (H1-0x= 19). When disabled, the Drive operates as a standard Drive that does not have PI
enabled.
Function: Com/Inv Sel 2
Setting: 6C
The Com/Inv Selection function allows the user to switch the origin of the Run and speed command between the Drive’s
terminals and the RS-485/422 port (and the embedded communication protocols) on the removable terminal board. When a
digital input is programmed for the Com/Inv Selection function (H1-0x= 6B) that input will function as follows:
