4. Standard Operation
The drive interface features 15 Analog Inputs, 23 Analog Outputs, 8 Binary Inputs and 10 Binary Outputs
for configuring, controlling, and monitoring its operation.
This chapter describes each aspect of operation, grouping the objects together by function. Objects are
summarized by type in Section 3, Application Overview.
4.1 Drive Configuration
This section describes the objects used to configure the drive. Refer to the appropriate Technical Manual
for additional information.
4.1.1 Accel/Decel Times – AO2, AO3
These analog outputs define the ramp rates for starting and stopping the motor, configuring the drive as
described below:

Object Name GPD505
Parameter
GPD506
Parameter
Units Default Min Max
AO2 Acceleration Time n019 n018 Sec 10.0 0 3600.0
AO3 Deceleration Time n020 n019 Sec 10.0 0 3600.0
4.1.2 PID Configuration – AO4, AO5, AO9
These analog outputs define the gains and mode of the PID controller. The PID modes selectable by A09
are described below:
AO9 PID Mode
0 PID Disabled
1 PID Enabled
2 PI with Feed Forward
3 Inverted PID
These objects configure the drive as described below:

AO4 PID Proportional Gain n086 n086 - 1.0 0.0 10.0
AO5 PID Integral Time n087 n087 Sec 10.0 0.0 100.0
AO9 PID Mode Select n084 n084 - 0 0 3
4.1.3 Stall Prevention – AO6, AO7
These analog outputs define the stall prevention levels during acceleration and run. Each value is specified
as a percentage of the drive’s current rating (AI14). If the output current (AI3) reaches the specified level
during acceleration or run, the output frequency is maintained or lowered as needed to sufficiently reduce
the output current. These objects configure the drive as described below:
