Receiving & Installation 3-13MN1854
Standby Current (can be changed at any time)
Setting the Standby current DIP switch to ON reduces motor current by 30% when
the drive has not received a step pulse for 250 msec. Full current is restored when
the next step pulse is received. Each drive can also be set to standby with the EA2
software command.
A 30% reduction in motor current during Standby correlates with an approximate
30% reduction in motor holding torque. Do not use Standby mode in applications
where you need more than 70% of the motor’s torque to hold a load stationary.
Standby should not be used in applications where an encoder is used to perform
end–of–move position maintenance.
Waveform (can be changed at any time)
On Sinusoid, Off for 4% 3rd harmonic.

Power On Checks
When power is first applied, the “ON” LED will be green. With the keypad
connected, the LCD display will briefly display the initialization screens.
Note: The LCD display may require contrast adjustment for better viewing. If the
display cannot be seen, adjust the potentiometer in Figure 3-15 for best
viewing.
