8-3-32. RLTC3 register
Latched data for COUNTER3 (deflection counter) or current speed. (Read only.)
The contents of COUNTER3 or the current speed are copied when triggered by the LTC, an ORG input,
or an LTCH command. When the LTFD in the RENV5 register is 0, the register latches the COUNTER3
data. When the LTFD is 1, the register latches the current speed. When the LTFD is 1 and movement on
the axis is stopped, the latched data will be 0.
Data range when LTFD is 0: -32,768 to +32,767.
Data range when LTDF is 1: 0 to 65535.
Bits marked with a "$" will be the same as bit 15 when LTFD (bit 14) in the RENV5 register is 0 (sign
extension), and they will be 0 when the LTFD is 1.
8-3-33. RLTC4 register
Latched data for COUNTER4 (general-purpose). (Read only.)
The contents of COUNTER4 are copied when triggered by the LTC, an ORG input, or an LTCH
command.
Data range: -134,217,728 to +134,217,727.
For details about the counter data latch, see section 11-10, " Counter."
Note 1: Bits marked with an "*" (asterisk) will be ignored when written and are 0 when read.
Note 2: Bits marked with an "&" symbol will be ignored when written and will be the same value as the
upper most bit among bits having no marks when read. (Sign extension)
