Z1-07: Speed Reference Select
Selects the frequency reference source 1.
Note:
1. Default is 1 in bypass controller software versions VST800298 and later. Default is 0 in bypass controller software versions VST800297
and earlier.
2. 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

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: Analog Input Terminals
Using this setting, an analog frequency reference can be entered as a voltage or current signal from terminals A1 or A2.
Voltage Input
Voltage input can be used at any of the two analog input terminals. Make the settings as described in
for the input
used.
