Note
A communication reference is a percentage expressed as a fraction of the maximum fre‑
quency (F0‑10). +10000 and –10000 correspond to +100.00% and –100.00% respectively. For
torque dimension data, this percentage is F2‑10 or A2‑48 (digital setting of torque upper
limit of the first or second motor).
