F11 - F15=019: DC Injection brake signal
The DC injection braking function time and start frequencies are set by parameters F37 and
F38. When the TM2 DC injection brake signal is OFF, and the internal brake timer (set by
F37) has not expired, the brake timer is reset to the value of F37.
When the TM2 DC injection brake signal is ON, and the internal brake time F37 has not
expired, DC injection braking is activated.
F16 AIN Signal select
000: 0 - 10V / 0 - 20mA (Set SW2 to the correct signal : V / I)
001: 2 - 10V / 4 - 20mA (Set SW2 to the correct signal : V / I)
F19 AIN bias
000: Positive
001: Negative
F20 AIN signal slope direction
000: Positive
001: Negative
C45 AIN signal scan time confirmation
(mSec × 8): 001
– 100
The AC drive processor reads A/D values every C45 x 8mS. The user can set the scan interval time to
suppress any noise levels caused by the operating environment. Extend C45 to increase the filter time if
noise is a problem, however the analog signal response will be slower.
F19= 000
: 0VDC (4mA) corresponds to lower frequency limit, 10VDC (20mA) corresponds to upper
frequency limit.
F19= 001
: 10VDC (20mA) corresponds to lower frequency limit, 0VDC (4mA) corresponds to upper
frequency limit.
