BASIC USES OF Σ-SERIES PRODUCTS
2.4.5 Minimum Parameters Required and Input Signals cont.
50
• For position control
Cn-02 bits 3, 4 and 5 Reference pulse form selection (see page 70)
Cn-24 Electronic gear ratio (numerator) (see page 81)
Cn-25 Electronic gear ratio (denominator) (see page 81)
When these parameters (except for Cn-03) are changed, always turn the power OFF,
then back ON. This makes the new setting valid.
If the specified direction of rotation differs from the actual direction of rotation, the wiring
may be incorrect. In this case, recheck the wiring and correct it accordingly. Then, if the
direction of rotation is to be reversed, set the following parameter:
Cn-02 (bit 0) Reverse rotation mode (see page 54)
After changing the Cn-02 setting, always turn the power OFF, then ON, to make the new
setting valid.
J Input Signals
The following table lists the minimum input signals required to conduct a test run. For de-
tails of each input signal, refer to the relevant page.
Signal Name
Pin
Number
Function
/S-ON (servo ON) 1CN-40
Switching between motor ON and OFF status. The
memory switch can be used to eliminate the need for
external short-circuit wiring (see page 131).
P-OT
(forward
rotation
prohibited)
1CN-42
Overtravel limit switch
The memory switch can be used to eliminate the
N-OT
(reverse
rotation
prohibited)
1CN-43
The memory switch can be used to eliminate the
need for external short-circuit wiring (see page 56).
