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.

Step Type (can be changed at any time) Not Used.

Anti–Res(can be changed at any time) Not Used.

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.
