4.12 Test Run Checklist
158 YASKAWA SIEPC71061753C GA500 Technical Manual
Checked No. Description
18
When you use terminal A2 for the frequency reference:
• Voltage input
– Set DIP Switch S1 on the drive to “V”.
– Set H3-09 = 0, 1 [Terminal A2 Signal Level Select = 0-10V (LowLim=0), 0-10V (Without Lower Limit)].
– Set H3-10 = 0 [Terminal A2 Function Selection = Frequency Reference].
• Current input
– Set DIP Switch S1 on the drive to “I”.
– Set H3-09 = 2, 3 [Terminal A2 Signal Level Select = 4 to 20 mA, 0 to 20 mA].
– Set H3-10 = 0 [Terminal A2 Function Selection = Frequency Reference].
19
Make sure that the frequency reference gets to the necessary minimum and maximum values.
If drive operation is incorrect, make these adjustments:
• Gain Adjustment
Set the maximum voltage and current values, then adjust the analog input gain until the frequency reference is at the necessary value.
– For terminal A1 input: H3-03
– For terminal A2 input: H3-11
• Bias adjustment
Set the maximum voltage and current values, then adjust the analog input gain until the frequency reference is at the necessary value.
– For terminal A1 input: H3-04
– For terminal A2 input: H3-12
