Special Instructions Section 5-26
Mode 0 (M=000) Mode 0 is used to output a specified number of CW or CCW pulses from port
1 or 2. The acceleration rate, frequency after acceleration, deceleration point,
deceleration rate, and frequency after deceleration can all be controlled.
PULS(65) Operand
Settings
PULS(65) must be executed before ACC(––) in order to specify direction, the
total number of pulses to be output, and the deceleration point. The function
of PULS(65) operands are described below. Refer to 5-26-9 SET PULSES –
PULS(65) for more details.
1,2,3... 1. The first operand of PULS(65) specifies the output port. Pulses are output
from port 1 when P=001, and from port 2 when P=002.
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.
1,2,3... 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 (M=001) Mode 1 is used to increase the frequency being output to a target frequency
at the specified rate. Pulse output continues until stopped.
The 2 control words indicate the acceleration rate and target frequency.
