If constant n037 is set to 3 (standard motor, motor 1 only) or 4 (special
motor, motor 1 only), however, OL1 calculations for motor 1 will
always be performed, regardless of the status of the Motor Switching
Command. (Regardless of whether motor 1 or motor 2 is selected, out-
put current detection data for motor 1 is calculated with the actual out-
put current, and output current detection data for motor 2 is calculated
with an output current of 0.0 A.)
• Maximum Frequency, Frequency Reference, Acceleration
Time, and Deceleration Time
When motor 1 is selected, operation is performed using n011 (Maxi-
mum Output Frequency) as the maximum frequency. Therefore, when
the set value of the Maximum Output Frequency (n011) and the set
value of the Motor 2 Maximum Output Frequency (n140) are different,
operation is as follows:
1. Even when using an analog frequency reference with the same refer-
ence voltage (current), the frequency reference will differ by the
ratio between n011 and n140.
Example: If n011 = 60 Hz and n140 = 50 Hz, when the reference
voltage is 5 V (50%), motor 1 would rotate at 30 Hz and motor 2
would rotate at 25 Hz.
