i.3 Modified Parameters
u H1: Multi-Function Digital Inputs
n H1-03 to H1-07: Functions for Terminals S3 to S7
These parameters assign functions to the multi-function digital inputs.
Note: Setting F is added and Setting 13 is removed for parameters H1-03 to H1-07 in bypass controller software versions VST800298 and later.

Table i.3 Added Multi-Function Digital Input Terminal Setting
Setting Function
F Not Used (Through Mode)
Setting F: Not Used (Through Mode)
Select this setting when using the terminal in a pass-through mode. When set to F, an input does not trigger any function in
the drive. Setting F, however, still allows the input status to be read out by a PLC via a communication option or MEMOBUS/
Modbus communications.

Setting Function
13 Jog Reverse
u H3: Multi-Function Analog Inputs
These parameters assign functions to multi-function analog input terminals: A1 and A2.
n H3-oo Multi-Function Analog Input Terminal Settings
Note: Setting 1F is “HAND Reference” in bypass controller software versions VST800298 and later. Setting 1F is “Not Used (Through Mode)”
in bypass controller software versions VST800297 and earlier.
Table i.5 Modified Multi-Function Analog Input Terminal Setting
Setting Function
1F HAND Reference
Setting 1F: HAND Reference
Sets the frequency reference when in HAND Mode and parameter Z1-41, HAND Speed Reference Selection, is set to 1
(Analog).
u L2: Momentary Power Loss Ride-Thru
n L2-01: Momentary Power Loss Operation Selection
When a momentary power loss occurs (DC bus voltage falls below the level set in L2-05), the drive can automatically return
to the operation it was performing prior to the power loss based on certain conditions.
Note: Default is 2 in bypass controller software versions VST800298 and later. Default is 0 in bypass controller software versions VST800297
and earlier.
