YASKAWA ELECTRIC SIEP C710616 38F YASKAWA AC Drive - L1000A Technical Manual 203
5.7 H: Terminal Functions
H parameters are used to assign functions to the external terminals.
◆ H1: Multi-Function Digital Inputs
NOTICE: Always turn off the RUN command before changing the setting of parameters d1-18 (Speed Reference Selection Mode),
b1-01 (Speed Reference Selection), or H1-
(Multi-Function Digital Inputs). If the RUN command is on when changing any of these
settings, the motor may unexpectedly start running, and could result in injury.
■ H1-03 to H1-08: Functions for Terminals S3 to S8
These parameters assign functions to the multi-function digital inputs. The various functions and their settings are listed
in Table 5.9.
Table 5.9 Multi-Function Digital Input Terminal Settings
Setting 3 to 5: Multi-Step Speed Reference 1 to 3
Switches multi-step speed frequency references d1-01 to d1-08 by digital inputs. Refer to Speed Selection Using Digital
Inputs (b1-01 = 0) on page 124 for details.
Setting 6: Jog reference selection
When the speed reference is not assigned to the input terminals (b1-01 ≠ 1), then the Jog frequency will be activated every
time an input terminal set for the Jog frequency reference closes. Note that the speed reference priority selection in d1-18
may disable the Jog frequency.
No.
<1> With the speed reference priority d1-18 is set to 0 or 3, the default settings for parameters H1-03 to H1-07 governing input terminals S3 to S7
are: 24, 14, 3, 4, and 5 respectively. When d1-18 is set to 1 or 2, the default settings for H1-03 to H1-07 become 50, 54, 51, 53, and F
respectively.
