(2) Response time of each signal
The response time of the X10 signal is within 2ms.
However, when the X10 signal is not assigned at the
[
Pr. 30 Regenerative function selection = 2 ] (FR-HC, MT-
HC, FR-CV connection), the response time of the
MRS signal is within 2ms in
, and [
Pr.
17 MRS input selection
] is invalid.
Response time of X10 signal and MRS signal in
is within 2ms.
(3) Changing the control logic
The input signals are set to sink logic (SINK) when
shipped from the factory.
In sink logic, a signal switches ON when a current
flows from the corresponding signal input terminal.
Terminal SD is common to the contact input signals.
In source logic, a signal switches ON when a current
flows into the corresponding signal input terminal.
Terminal PC is common to the contact input signals.
1) Changing the control logic for
To change the control logic, the jumper connector
on the back of the control circuit terminal block
must be moved to the other position. (The output
signals may be used in either the sink or source
logic independently of the jumper connector
position.)
(a) Loosen the two installation screws in both
ends of the control circuit terminal block.
(These screws cannot be removed.)
Pull down the terminal block from behind the
control circuit terminals.
(b) Change the jumper connector set to the sink
logic (SINK) on the rear panel of the control
circuit terminal block to source logic
(SOURCE).
(c) Using care not to bend the pins of the drive
unit's control circuit connector, reinstall the
control circuit terminal block and fix it with the
mounting screws.
2) Changing the control logic for
To change the control logic, the jumper connector
above the control terminal must be moved to the
other position.
Change the jumper connector in the sink logic
(SINK) position to source logic (SOURCE)
position using tweezers, a pair of long-nose pliers
etc.
Change the jumper connector position before
switching power ON.
