3.3 Modified Programming Parameters
8 ACCEL and 9 DECEL The largest value that can be transmitted using the P1 protocol is 32767. It
was therefore necessary to limit the maximum value for these parameters to
3000.0 seconds.
24 AUTO SOURCE The default selection for this parameter has been changed to KEYPAD. Refer
to Section 3.4 Serial Communications Setup for more information.
32 HZ MULTIPLIER The default setting for this parameter has been changed to 30.00. Refer to
Section 3.4 Serial Communications Setup for more information.
57 SERIAL The default selection for this parameter has been changed to WITH TIMER to
provide limited “out-of-the-box” serial communication with the drive.
58 SERIAL ADDRESS The minimum and maximum values for this parameter have been changed to
0 and 99, respectively, in accordance with the Siemens P1 Protocol Design
Specification. The default value has also been changed to 99. Refer to Section
3.4 Serial Communications Setup for more information
3.4 Serial Communications Setup
The factory default values for all drive parameters are setup to allow immediate serial communications
(without serial start and serial speed/setpoint commands). For serial speed/setpoint and/or serial start
control, modify the setting of Drive Parameter #30 (Control). The drive parameters that are required for
serial communications, including Drive Parameter #30, are described below.
24 AUTO SOURCE must be set to KEYPAD for the drive speed/setpoint to be modified over the FLN.
30 CONTROL should be set to accommodate the specific application intent:
NORMAL Serial start and serial speed/setpoint commands are invalid.
NORM NO HAND Same as NORMAL except the HAND/OFF/AUTO, herein
referred to as H/O/A, is limited to settings of OFF and AUTO.
SERIAL SPEED Serial start commands are invalid. Serial speed/setpoint
commands are valid in AUTO H/O/A.
S SPD/NO HAND Same as SERIAL SPEED except H/O/A is limited to settings of
OFF and AUTO.
SERIAL AUTO Serial start and serial speed/setpoint commands are all valid
in AUTO H/O/A. This setting forces the drive to be started over
the FLN when in AUTO H/O/A.
S AUTO/NO HND Same as SERIAL AUTO except H/O/A is limited to settings of
OFF and AUTO.
Serial STOP commands are accepted from the FLN regardless of the setting of Parameter 30.
