Omron SMARTSTEP SERVO DRIVE - Page 6

158 AC servo systems
Enable switch/parameter setting
Pin 6 of the DIP switch selects whether the servo drive operates according to the
DIP switch settings or parameter settings
.
Online autotuning setting
The autotuning switch selects whether the gain will be adjusted auto-
matically during operation.
Resolution setting
Pins 4 and 5 select the positioning resolution.
If the resolution is set to 1,000 (the default setting), the motor makes
one revolution for every 1,000 pulses input.
Command pulse input setting
Pin 3 selects the command pulse mode. Select “Forward pulse/reverse
pulse: positive logic” or “feed pulses/direction signal: positive logic.”
Dynamic brake setting
Pin 2 enables or disables dynamic brake operation. If the dynamic brake is ena-
bled, the motor can be brought to an emergency stop when the RUN command
goes OFF or an alarm occurs.
Alarm Table
Note: 1. These parameters are read when the power is turned
ON. Parameter Pn110.2 is valid when online.
2. When using a regeneration resistor, set the resistor’s
capacity when the temperature has risen to 120 °C.
Set this parameter to 0 if a regeneration resistor is not
being used.
Pin 6 Function
OFF Enables the DIP switch settings.
ON Enables the parameter settings.
