PARAMETER SETTING AND OPERATION OF PULSE/ANALOG INPUT

INPOS Signal Setting

The "Inposition(INPOS)" signal is output when the absolute value of the difference between the pulse command from the

higher-level equipment and the movement of servo motor is lower than the set value.

For "INPOS" wiring, see "4-5 Wiring I/O Signals", Page 4-24.

■ INPOS range

The range of "INPOS" signal pulse has to be set up.

Please see "5-2 Common Function Setting", Page 5-4.

■ INPOS/NEAR unit

The number of pulses set in INPOS/NEAR range can be set to the command pulse unit of higher-level equipment or

encoder pulse (feedback pulse) unit of servo motor.

For details, see "5-2 Common Function Setting", Page 5-4.

■ INPOS output timing

According to the size of INPOS range, when position deviation in use is always in smaller status, "INPOS" output is

always ON. For command pulse input, in order to enable "INPOS" output to OFF, output timing of "Inposition (INPOS)"

signal must be changed.

For the setting, see "5-2 Common Function Setting", Page 5-4.

Positioning Approximation Signal (NEAR) Setting

The "Positioning approximation(NEAR)" signal is output when the absolute value of the difference between the pulse

command from the higher-level equipment and the movement of servo motor is lower than the set value.

For "NEAR" signal wiring, please see "4-5 Wiring I/O Signals", Page 4-24.

■ INPOS/NEAR unit

The number of pulses set in INPOS/NEAR range can be set to the command pulse unit of higher-level equipment or

encoder pulse (feedback pulse) unit of servo motor can be used.

For details, see "5-2 Common Function Setting", Page 5-4.

Torque Limit Setting

A torque limit is applied on the servo motor by inputting a torque limit value based on analog voltage or internal torque

limit into the servo amplifier.

■ Torque limit method switching

Three methods are available, namely "Internal torque limit (basic)", "Internal torque limit (extend)" as well as "Analog

torque limit".

These can be set up with parameters.

For details, see "5-2 Common Function Setting", Page 5-4.

Deviation Excessive Alarm/Warning Setting

In case the absolute value of the difference between the pulse command from the higher-level equipment and the

movement of the servo motor is higher than the set value, an alarm or warning occurs. In this case, the "ALARM" or

"WARN" output is ON.

For the setting, see "5-2 Common Function Setting", Page 5-4.
