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 target frequency. C+1 must be BCD from
0000 to 5000 (0 Hz to 50 kHz).
Mode 2 (M=002) 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.
The 2 control words indicate the deceleration rate and target frequency.
1,2,3... 1. The content of C determines the deceleration rate. During deceleration,
the output frequency is decreased 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 3 (M=003) Mode 3 is used to decrease 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.
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 target frequency. C+1 must be BCD from
0000 to 5000 (0 Hz to 50 kHz).
Flags ER: There is an error in the operand settings.
The CPU Unit is not a CQM1-CPU43-EV1.
The PC Setup is not set for pulse output.
ACC(––) is executed with M=000 and the specified output port is in
use.
ACC(––) is executed in an interrupt subroutine while a pulse I/O or
high-speed counter instruction is being executed in the main program.
Indirectly addressed DM word is non-existent. (Content of *DM word
is not BCD, or the DM area boundary has been exceeded.)
AR 0515: Port 1 output flag. ON when pulses are being output from port 1.
