iQpump Basic Programming Parameters
The initialization group contains parameters associated with initial set-up of the Drive. Parameters involving the display language, access
levels, initialization and password are located in this group.
◆ A1 Initialization
■
A1-01 Access Level Selection
If the iQpump drive is programmed for Operation Only (A1-01 = “0: Operation Only”), then only the OPERATION and the
PROGRAMMING menus are accessible. Within the PROGRAMMING menu only parameters A1-01 and A1-04 are adjustable.
If A1-01 is configured for Advanced Access (A1-01 = “2: Advanced Level”), then all menus and all parameters are shown. If the Access
Level Selection is set to Advanced, all parameters should be adjustable unless:
1. The iQpump drive parameters are password protected (A1-04) which will prevent access to A1-00 through A1-03 and all A2
parameters.
2. A digital input has been configured as a Program Lockout (H1-0X = 1B) is active.
3. During serial communication writing, if a parameter change is also attempted via the digital operator, a “BUSY - WRITE
PROTECTED” message will display. Parameter change will not be possible from the digital operator until an Enter command is
received via the serial communication to finish the serial writing process.
■
A1-03 Initialize Parameters
The iQpump drive can be set back to one of three default states via the A1-03 parameter.
1. User Initialization – 1110: The modified iQpump drive parameters are returned to the values selected as user settings. User settings are
stored when parameter o2-03 = “1: Set Defaults”.
2. 2-Wire Initialization – 2220: The iQpump drive parameters are returned to factory default values with digital inputs S1and S2
configured as Forward Run and Reverse Run, respectively.
3. 3-Wire Initialization – 3330: The iQpump drive parameters are returned to factory default values with digital inputs S1, S2, and S5
configured as Run, Stop, and Forward/Reverse respectively.
After an initialization is performed, parameter A1-03 will automatically be set back to 0.
