Notes: 1. Off: The brake function does not operate.
Brake 1: Braking up to No/8.
Brake 2: Braking up to No/8, and then regenerative braking.
Brake 3: Regenerative braking. The No/8 signal is output.
During a braking operation, when the MR frequency when braking completes cannot be detected
in the circuit (During braking, the speed detection signal for under setting is not output over the
2/D1 occurrence. Thus this occurs more easily for lower settings.), reverse rotation may continue
in some cases. Note that this bit is also used to set the rotation monitor output (FH × 3 or the MR
frequency). FH × 3 is only output from the rotation monitor when motor on (MD0 = 1) and brake 3
are selected.
2. The ready setting range has the following manufacturing variation:
4.3% ±25% (@MD4 = 1)
8.6% ±25% (@MD4 = 0)
3. This function masks the current limiter input (pin 27) (incorrect operation due to the recovery
current). See page 20 for details.
4. The PLL output setting indicates a change relative to 3.5 Vp-p. See the electrical characteristics.
This is valid when MD9 = 0 (PLL control). Note that DD4 also functions as the Icp selection in
discriminator control mode.
