Commissioning and Trial Run
‑81‑
70: Control channel selection
The terminal is used to select one of two user‑defined command channels. Value 0
represents channel 1, and value 1 represents channel 2.
71: Setting channel selection (reserved)
72: Terminal module A/B selection
The terminal is used to select one of two terminal modules. Value 0 represents
module A, and value 1 represents module B.
73 and 74: Start mode (bit 0/bit 1)
The terminal is used to select a start mode. For example, if DI1 and DI2 are assigned
with functions 73 and 74, respectively: direct start is selected when both DI1 and DI2
are inactive; flying start is selected when DI1 is active but DI2 is inactive; DC braking
start is selected when DI1 is inactive but DI2 is active; and the last start mode is
selected when both DI1 and DI2 are active.
75: Control command switchover terminal 3
The terminal is used to switch the command source between the terminal/
communication control mode and user‑defined operation commands.
77: Running permission
When the terminal is active at high level, running is allowed. Otherwise, running is not
allowed or the AC drive must stop according to the setting of AA‑09 (stop mode during
running).
78: Forward running permission
When the terminal is active at high level, the frequency reference is allowed to be a
positive value. Otherwise, the positive frequency reference is reset to zero.
79: Reverse running permission
When the terminal is active at high level, the frequency reference is allowed to be a
negative value. Otherwise, the negative frequency reference is reset to zero.
80: Set RFG input to zero
When the terminal is active at low level, the target reference is reset to zero. When the
terminal is inactive at high level, the target reference is restored to its original setting.
86: Breakage detection (wire drawing machine)
After the AC drive is started and the time set by A7‑32 (Breakage detection time for
startup delay) expires, detection on the DI status starts. If the DI is active, the AC drive
reports E31.2 (breakage detection fault).
