2. The second operand specifies the direction. The output is clockwise (CW)
when C=002 and counter-clockwise (CCW) when C=003.
3. The third operand specifies the first of 4 control words.
a) The 8-digit content of N+1, N (0000 0001 to 1677 7215) determines
the total number of pulses that will be output.
b) The 8-digit content of N+3, N+2 (0000 0001 to 1677 7215) determines
the deceleration point.
ACC(––) Control Words
The 4 control words indicate the acceleration rate, frequency after accelera-
tion, deceleration rate, and frequency after deceleration.
1. The content of C determines the acceleration rate. During acceleration, the
output frequency is increased by the amount set in C every 4.08 ms. C
must be BCD from 0001 to 0200 (10 Hz to 2 kHz).
2. The content of C+1 specifies the frequency after acceleration. C+1 must
be BCD from 0000 to 5000 (0 Hz to 50 kHz).
3. The content of C+2 determines the deceleration rate. During deceleration,
the output frequency is decreased by the amount set in C+2 every 4.08 ms.
C must be BCD from 0001 to 0200 (10 Hz to 2 kHz).
4. The content of C+3 specifies the frequency after deceleration. C+3 must
be BCD from 0000 to 5000 (0 Hz to 50 kHz).
Mode 1 is used to increase the frequency being output to a target frequency
at the specified rate. Pulse output continues until stopped.

acceleration
The 2 control words indicate the acceleration rate and target frequency.
1. The content of C determines the acceleration rate. During acceleration, the
output frequency is increased by the amount set in C every 4.08 ms. C
must be BCD from 0001 to 0200 (10 Hz to 2 kHz).
2. The content of C+1 specifies the target frequency. C+1 must be BCD from
0000 to 5000 (0 Hz to 50 kHz).
Mode 2 is used to decrease the frequency being output to a target frequency
at the specified rate. Output stops when the total number of pulses specified
in PULS(65) have been output.
