PLC Analog Control
The PLC Analog Control wizard allows an external device to control motor speed with an analog signal
and optionally control motor start/stop using a digital input. Execute the PLC Analog Control wizard to put
Apollo into this
“dumbed down” mode.
To execute the wizard, from the Home Screen select:
Settings -> Menu -> Other Initial Setup -> Next Page -> Next Page -> Configuration Wizards -> PLC Analog
Control. Note: If you just need start/stop control
and don’t need analog speed control, select the 2-wire
RunStop wizard.
Follow the on-screen directions.
Information needed by the PLC Analog Control wizard:
• Analog Input to use for Speed Control:
– Options are V7 Analog 1, V7 Analog 2, EIO Analog Option 1, EIO Analog Option 2.
• Analog Input Offset (desired pump speed when input is 0V/4mA ).
• Analog Input Span (desired pump speed range,pump speed when input is 10V/20mA minus pump speed
when input is 0V/4mA. For example, (with a 4-20mA input) if the desired pump speed at 4mA is 30Hz and
the desired pump speed at 20mA is 65Hz, set the Offset to 30 Hz and the Span to 35Hz.
• You will be asked if want to use 2-Wire Stop/Start control. If you choose yes, the 2WireRunStop Wizard
will be executed from within the PLC Analog Control Wizard. See information on 2-wire Stop/Start Wizard
below.
This wizard changes the Drive Mode to
“Analog Follower”. To restore local frequency control, change the
Drive Mode to
“Manual Frequency” or any other Drive Mode. (Settings -> Menu ->Set Drive Mode->Drive
Mode). The Drive Mode setting does not affect operation of the 2-Wire Run/Stop feature.
