Input Signal Function
22
off
No momentary power failure detection by
digital input
on
Momentary power failure detection by
digital input
Torque control cancellation (Hz/TRQ)
Value 23: If function code H18 Torque control is set to
active (value = 1 or 2), this operation can be cancelled
externally by assigning 23 to the target digital input
terminal and switching between active and inactive for
this input signal.
Input Signal Selected Function
23 [Related Function: H18]
off Torque control function active – the input voltage to
Terminal 12 is the torque command value
on Torque control function inactive - the input voltage to
Terminal 12 is the frequency command value. PID
feedback amount when PID control operation is
selected (H20 = 1 or 2).
Link Operation selection (LE)
Value 24: Frequency and operation commands from the
data communications link can be enabled or disabled by
switching the external digital input signal. Select the
command source in H30-Link function and assign 24 to
the target digital input terminal to enable or disable
commands in this input signal state.
Input Signal Selected Function
24 [Related Function: H30]
off Link command disabled
on Link command enabled
Universal DI (U-DI)
Value 25: Assigning 25 to a digital input terminal renders
the terminal a universal DI terminal. The ON/OFF state of
signal input to this terminal can be checked through the
RS485 and BUS option.
This input terminal is only used to check for an incoming
input signal through communication and does not affect
drive operation.
Pick up start mode (STM)
Value 26: The (pick-up start mode): in function code H09
can be enabled or disabled by switching the external
digital input signal. Assign 26 to the target digital input
terminal to enable or disable the function in this input
signal state.
Input Signal Selected Function
26 [Related Function: H09]
off Start characteristic function disabled
on Start characteristic function enabled
SY-PG enable (PG/Hz)
Value 27: This selects the closed loop control with PG
(encoder) or open loop control.
Input Signal Operation Select
27
off
open loop control
on close loop control
Note: PG Option Card is required for this function
Zero speed command (zero)
Value 29: This function is used for stall torque operation
with vector control at zero.
Input Signal Selected Function
29
off
zero speed control disabled
on zero speed control enabled
Note: PG Option Card is required for this function
Timed alarm stop command (STOP1)
Timed alarm stop command with deceleration
time 4 (STOP2)
Value 30, 31: Disconnecting STOP1 and CM during
operation, the drive decelerates and stops by a present
deceleration time (STOP1)/deceleration time 4 (STOP2)
setting and then outputs alarm Er6 which is latched
internally and cleared by RST input. ON input is assumed
when this terminal function is not set.
Pre-exciting command (EXCITE)
Value 32: When EXCITE transition ON, the motor enters
into a pre-exciting state during flux vector control mode.
When an operation command (FWD or REV) is initiated,
the motor returns from the pre-exciting state to the
ordinary state.
Note: PG Option Card is required for this function
