Detailed Function Description

(12) Forced Pulse Output
(12) Sequence test mode
It is possible to simulate a servomotor connected state even when not connected.
Doing so allows host program debug work to be carried out efficiently.
Precautions

The conditions under which operation is possible, as well as the input/output signal functions are
the same as when the servomotor is connected.

One of the conditions for operation is that the main power supply (L1, L2, L3) must be supplied to
the servo amplifier.

Simulation is carried out based on the encoder bit count, and therefore the encoder bit count
must be set.

Current does not flow to the servomotor (furthermore, the main circuit transistor does not turn on
and off.)

The motor current, effective torque, OL thermal value, and regenerative resistor thermal value do
not change.

The overload forecast function does not work.

The INC/ABS system selection (PA1_2) is handled internally as 0: INC (simulation is not
possible with ABS systems.)

When exiting sequence test mode, turn off the servo amplifier control power (L1C, L2C).
Select the pulse signal to be output at (a).
A-phase, B-phase
By setting the frequency and pressing the [Forced Pulse
Output] button, a pulse is output.
Frequency setting range: 0 to ±1,000[kHz], 1[kHz]
increments
Z-phase
The Z-phase signal changes each time the [Forced H
Signal Output]/[Forced L Signal Output] buttons are
pressed.
Turn off the power to cancel this mode.
