Setting 4: HAND-BYPASS
When drive powers up , the bypass will get a "HAND" command and needs an "OFF" command to stop.
n Z1-07: Speed Reference Select
Selects the frequency reference source 1.
Note: If a Run command is input to the drive, but the frequency reference entered is 0 or below the minimum frequency, the AUTO or HAND
indicator LED on the HOA keypad will light and the OFF indicator will flash.
No.
Z1-07
Setting 0: HOA Keypad
Using this setting, the frequency reference can be input by:
• switching between the multi-speed references from d1-01 to d1-04.
• entering the frequency reference on the operator keypad.
Setting 1: Terminals (analog input terminals)
Using this setting, an analog frequency reference can be entered as a voltage or current signal from terminals A1, A2, or A3.
Voltage Input
Voltage input can be used at any of the three analog input terminals. Make the settings as described in
used.
