Input Signals That Can Be Allocated to CN1-14 and CN1-15
Relationship between Parameter Settings, Pin Numbers, and Polarity
The polarity of the signals that you allocate to CN1-14 and CN1-15 are set in separate param-
eters. You can set the signal polarity in Pn634 = n.X (SI8 Signal Selection Logic).
Note: Refer to the following section for details on input signal parameter settings.
9.2.2 List of Parameters on page 9-4
Example of Changing Input Signal Allocation for CN1-14 and CN1-15
The following example shows how to change the allocation of the Return Deceleration Switch
signal (/DEC) to CN1-14 and CN1-15 to allocate the Registration Input (/RGRT) instead.
Confirming Input Signals
You can confirm the status of input signals on the I/O signal monitor. Refer to the following sec-
tion for information on the I/O signal monitor.

Output Signal Allocations
You can allocate the desired output signals to pins 25 to 30 and 37 to 39 on the I/O signal con-
nector (CN1). You set the allocations in the following parameters: Pn50E, Pn50F, Pn510,
Pn512, Pn513, Pn514, Pn517, Pn635, and Pn636.

A reverse signal (a signal with “/” before the signal abbreviation, such as the
/DEC signal) is active when the contacts are ON (closed).

A reverse signal (a signal with “/” before the signal abbreviation, such as the
/DEC signal) is active when the contacts are OFF (open).
Before Change: Pn634 = n.2

After Change: Pn634 = n.3
The wiring specifications for CN1 connector terminals 15-14 and 40 to 47 are different.
Refer to the following section for information on the wiring the terminals.
3.2.3 I/O Circuits on page 3-8
The SERVOPACK may fail if the terminals are wired incorrectly.
Important
• The signals that are not detected are considered to be OFF. For example, the /COIN (Position-
ing Completion) signal is considered to be OFF during speed control.
• Reversing the polarity of the /BK (Brake) signal, i.e., changing it to positive logic, will prevent
the holding brake from operating if its signal line is disconnected. If you must change the polar-
ity of this signal, verify operation and make sure that no safety problems will exist.
• If you allocate two or more signals to the same output circuit, a logical OR of the outputs will be
used and all of the allocated signals will operate accordingly. This may result in unexpected
operation.
